As it is known, currently, the fields at the last stage of development are operated predominantly with sucker-rod pumps. Their operation is usually carried out in quite complicated technological and hydrodynamic conditions dramatically affecting the operation efficiency. Based on the actual field data, the paper studies the possible impact of the depth of sucker-rod pump running on the delivery rate, which is one of the indexes of operation of the whole sucker-rod pump unit. The values of delivery rates by oil and water have been calculated and their functional dependencies on the depth of sucker-rod pumps running developed as well. The results justified the increase of delivery rate by oil and its decrease by water in reviewed value diapasons. Mathematical models of developed dependencies have been obtained as well. As a result of conducted studies, the practicability of the increase of pump setting depth in operation conditions of reviewed field is justified.

In order to complete the numerical simulation on internal flow and operating characteristics of down hole multiphase pump compress unit, establishing perfect finite element model, the three-dimensional turbulent current fields inside the impellers of compression unit for down hole multiphase pumps were simulated by using ANSYS. The calculation of multiphase flow is based on the standard k-ε turbulent current model. Reference information for the improvement of the pump can be obtained by the analysis of the flow of gas-oil in the channel of pump. Based on the finite method, we analyzed several situations in a pumping period. The velocity and liquid pressure distributing of sucker rod pump is studied in this paper, which may offer some evidences for the engineering design of sucker rod pump.

Despite of the increased share of oil wells equipped with submersible electrical centrifugal pumps, a considerable part of them is equipped and operated with sucker-rod pumping units. When operating wells with sucker-rod pumping units, different plunger pumps are used. The rod string is operated in severe environment due to long contact with highly corrosive well products and time-variant loads. Taking into account all acting loads, the diagnostics of the condition of sucker-rod pumping units is a difficult task. At the majority of oil fields in Russia, the operation of wells equipped with sucker-rod pumping units is controlled by portable and stationary dynamographs of various models. Moreover, dynamographs are used, as a rule, only to obtain images of dependence of the force on the polished piston rod upon its stroke. Based on dynamograms it is possible to find the well flow rate, pump capacity, force on the polished piston rod, etc. But one of the main problems to be solved with the help of dynamometry is the forecasting of down-hole equipment condition in the process of further operation. In this paper we overview the methods to diagnose the condition of sucker-rod pumping units based on dynamograms. The aim of the work is to develop the mathematical model to forecast the failures of down-hole pumping equipment on the results of dynamometry to automatize the control process of the unit operation. The research tasks are to analyze the existing methods for diagnosing the condition of sucker-rod pumping units, and to develop the mathematical model for forecasting the failure of the valve unit leakage. As a result, the method for forecasting the increased failure on the example of the fluid leakage in the pump injection unit is proposed. The permissible boundaries of the change in the relative force on the polished piston rod are drawn up. As a result, the failure increase is forecasted based on the frequency of the relative force on the polished piston rod getting within the interval obtained.

One of the factors decreasing the operation efficiency of wellhead pump unit is the fluid loss from the starting space between the pump, barrel coupling and the plunger. Due to the the pressure of liquid column rising within the barrel, as well as the friction wear over time, the space between the barrel-plunger pair increases, significantly amplifiying the fluid loss. The pressure within liquid columns on the inner and outer barrel surfaces should be aligned to prevent their widening due to the pressure. The space increases due to the hydrostatic pressure in the pumps in the upper parts of the barrel coupling, thus the fluid leakeage increases as well. In case, when the barrel coupling is in the lower part of cylinder, due to the pressure in the liquid column from within and outside, the space does not increase and as a result the well production rate rises for up to 3 %.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 200825, “Failure Prediction for SRP Using Analytic Solutions,” by Viorica Sirghii, SPE, Rudolf Konrad Fruhwirth, and Herbert Hofstaetter, University of Leoben, et al. The paper has not been peer reviewed. A method for prediction of sucker-rod-pump (SRP) failure based on improved, completely connected perceptron (ICCP) artificial neural networks (ANNs) is presented. Results are compared with historical wellbore data. The validity of the ANN model is proved to meet SRP failure prediction with a ±5% error, helping identify and prevent potential damage, reduce costs and risks, and optimize production. SRP Diagnosis To evaluate the performance of SRPs, dynamometer cards are used. The load on the top rod is measured and plotted in relation to the polished rod position as the pumping unit moves through each stroke cycle. The result is a surface card that illustrates the polished rod load vs. position (downhole diagnostics). To determine above-pump liquid accumulation, pump-filling efficiency, and displacement, the well’s producing and lifting efficiencies can be analyzed and quantified. Depending on the results, operational and equipment changes can be made to improve efficiency and production optimization. How the plunger picks up, holds, and releases the fluid load at each stroke can be seen in a dynamometer card’s shape. The most-common and most-harmful pump states are fluid pound, gas interference, and tagging. When the pump is not completely full, the rod string is damaged because of an excessive number of strokes.

The most widespread mechanized way of oil production is use of sucker rod deep pumping units. This mode of well operation is characterized by moderate costs of the equipment and its service, increase in production when developing difficult-to-recover oil reserves, increase in production of layer which is reached by decrease in critical bottom hole pressure. Installation of the sucker rod deep pump comprises the land and borehole equipment. The drive, the well head setup and control system belongs to the land equipment. For today the pump unit is used as a wire. The unit itself represents the four-link crank-and-rod mechanism converting crank rotational motion into reciprocal motion of polished rod carrier bar. The work considers the prospects of creation and implementation of the drives nonconventional designs replacing classical pumping units, namely hydraulic actuators of sucker rod deep pumps on Ukrainian oil fields. Furthermore, the possible fields of their use has been defined. The hydraulic pressure drives existing designs presented by the leading global manufactures have been analyzed via critical-comparative method. Moreover, their design features in comparison with pumping units and chain occasions have been covered, the main advantages and shortcomings have been revealed. The usage possibilities of remote and automatic control of the hydraulic pressure drive working mode have been specified. The drive allows to carry out monitoring and remote control of technological process in real time with the minimum participation of service staff. The work presents the results of the hydraulic pressure drive PSHN-80-2.5 with pneumatic equilibration pilot test on well 64-Dolyna of scientific testing ground of the Ivano-Frankivsk National Technical University of Oil and Gas which have confirmed the work capacity of all drive systems and also convenience of carrying out the installation operations.

Full textAbstract:
The efficiency of sucker rod pump installations, which have become widespread in mechanized lift practice, is largely determined by the balance of the drive. During the operation of sucker rod installations, the balance of loads acting on the rod string and the drive can change significantly due to changes in the dynamic fluid level, which leads to a decrease in balance and an increase in loads on the pumping equipment units. The increase and decrease in the dynamic level in accordance with the pumping and accumulation cycle occurs in wells operating in the periodic pumping mode.
It is shown that during the operation of equipment in a periodic mode, fluctuations in the dynamic level and, accordingly, in the loads acting on the nodes occur. This leads to the need for dynamic adjustment of the balancing weights to ensure the balance of the pumping unit. A system for automatic balancing of the rod drive has been developed, including a balancing counterweight, an electric motor that moves the load along the balance beam, a propeller and a computing unit.
To study the effectiveness of the proposed device, a complex mathematical model of the joint operation of the reservoir - well - sucker rod pump - rod string – pumping unit has been developed. It is shown that due to the dynamic adjustment of the balance counterweight position, the automatic balancing system makes it possible to significantly reduce the amplitude value of the torque on the crank shaft (in comparison with the traditional rod installation) and provide a more uniform load of the electric motor. Equalization of torque and motor load reduces the power consumption of the unit.

The purpose of this paper is to analyze the power efficiency of oil well systems with sucker rod pumping units. For this study a chain-drive of HRC 80-6-02 type and a similar performance drive HRC 80-6-02 balancer pumping unit were selected. Based on the analysis of the data, a conclusion was made that the power consumption for production of oil using ESP units is much higher due to a low coefficient of performance (COP) and significant losses in the submerged electric-driven pump. The analysis showed that for a half cycle of operation, i.e. per one stroke, the power consumption by a jack-pump was 15-20% higher than that of the chain drive. It is concluded that the chain drive is superior in many aspects of sucker-rod pumping units operation and may be the most effective replacement for ESP units, as well as for units with walking-beam jack pumps.

Full textAbstract:
To increase the efficiency of the use of a sucker rod pumping unit (SRPU) today the columns of sucker rods of fiberglass and carbon fiber are used. Such polymer composites have a number of advantages over steel, but they have a significant drawback in the design of a sucker rod - a high concentration of stresses at the point where theyare connected to a steel head containing a thread. Many constructive solutions to this problem have been developed, but maintaining the connection of a fiberglass or carbon-plastic barrel with a metal head remains quite a challenge. As practice shows, the bending of the pump rods in the well are also subjected to bending loads, torque, friction to the column of tubing (tubing) and the like. Therefore, a comparative analysis of the parts of the pump rod structures: traditional steel and combined (metal tip with composite rod) should be carried out. In this work, such joints were subjected only to bending loads, which are particularly dangerous when passing through a rod of bent sections of a well and when running down the bar. It is established that at the time of bending the maximum normal stresses are distributed along the length of the pump rod unevenly and are concentrated in the transition between the head and the rod. The maximum normal stresses occurring in the transition between the steel tip and the carbon-plastic core, which are jointed without structural features (galtels, different transitions, etc.), have been determined to be greater than 1600 MPa. Such value of stress is undesirable when cycling the connection in well. For example, the design of a metal head was proposed, which allows reducing the stresses arising from bending and distribute them on the connection more evenly, compared to the traditional sucker rod.

Full textAbstract:
The article presents the results of experimental studies to assess the loading and balancing of a new constructive solution of beamless sucker-rod pumping units. It is noted that the key factor that has the most significant effect on the mean time between failures (MTBF) is the right balancing of the pumping unit. The main purpose of the balancing device is the accumulation of potential energy during the downstroke and its release during the upstroke of the rod. It has been proved that the proposed additional balancing system (movable counterweight) which helps to reduce the uneven load on the electric motor and the power consumption of the pumping unit will also increase the efficiency of the beamless sucker-rod pumping unit. It was found that losses in sucker-rod pumps depend on the degree of balance of the counterweights. If the unbalance coefficient of the equipment is in the range from –5 to +5%, then the power loss due to unbalance can be ignored. In the current article, the authors propose a technique that allows to determine the energy characteristics of the electric drive of the pumping unit under conditions of a cyclically changing load and insufficient balance. It was revealed that when the balancer head passes from the upstroke to the downstroke and vice versa, there are sections with a negative value of the torque, which is explained by the influence of the inertial forces of the moving masses. This leads to shocks in the gearing of the reducer at the extreme positions of the cranks, increased wear and possibly to breakage of the teeth. Since it is not possible to completely eliminate this phenomenon, one should strive to limit the value of the negative torque by the correct balancing of the sucker-rod pump. In all cases, the change in the operating mode of a new constructive solution of beamless pumping unit requires new calculations, and requires changing the position and weights of movable and rotary counterweights (with combined balancing).

Full textAbstract:
The development of fields that are at a late or final stage of operation is carried out mainly with the use of downhole sucker rod pumps. The most characteristic failures for these installations are rods parting-twist off and malfunctions of pump valves. The methods of eliminating these accidents vary significantly the parting or twist off of the rods involves lifting of the downhole equipment, and the "sticking" of the shut-off valve assembly of the pump is eliminated by "resuscitation" of the downhole equipment (flushing with water, hot oil or solvent). An error in fault identification leads to incorrect planning of work to restore the operability of the downhole equipment and, as a result, to economic losses.
The cause of malfunctions of the downhole equipment of downhole rod pumping units, as a rule, is determined by analyzing dynamograms. However, in many cases dynamograms do not allow to distinguish the lower twist off of the rods from the malfunction of the valves of the rod pump. In the presented work, a method for the operational determination of the parting or twist off of rods in the well is considered, which consists in creating an electrical circuit "rod string tubing string" and monitoring its integrity. To determine the type of malfunction, the synchronization unit measures the resistance of the system on the dielectric insert via the electromagnetic channel. In case of parting or twist off of the rods, the electrical resistance of the "tubing-pump-rod string" circuit will be much higher (more than 2 ohms) than in the absence of this failure (0...2 ohms).

The technology for pumping out and partial utilization of associated gas in oil fields by the vacuum method, using a unit for pumping gas from the annulus of the well and pumping it into the product collection system (KOGS), have been implemented at wells at the Zarechnoye field of Geotech JSC in the Republic of Tatarstan. These wells are operated by sucker rod units. The use of the KOGS unit allowed us to evaluate the effectiveness of the production system under consideration Experimental studies have shown that a decrease in annular pressure causes a significant increase in the dynamic level and an improvement in the conditions of oil inflow to the well. The operation of sucker rod units in such conditions provides an increase in the delivery and filling coefficients of the pump and, accordingly, an increase in oil production.

Aiming at the defects of fault diagnosis in the traditional method for sucker rod pump system, a new method based on support vector machine (SVM) pump fault diagnosis is proposed. Through studying the theory of invariant moment and the shape characteristics of pump indicator diagram, seven invariant moments is extracted from the indicator diagram as a pumping unit well condition of the characteristic parameters. Then these parameters are pretreatment, and it makes up seven eigenvector which are regarded as the input eigenvector of the SVM. The experiment indicates that the method can not only detect the fault of the pumping oil well but also can recognize the fault type of it, which is very effective for safety protection and fault diagnosis of the pumping oil.

Modern trends in the development of technology are based on the need for experimental studies of the equipment being developed in laboratory conditions with the maximum approximation of the operating modes to real ones. Such studies are impossible without the development of specialized stands with test automation systems. Automation of processes involves the organization of measuring channels as part of a stand using analog-to-digital conversion (ADC), digital-to-analog conversion (DAC), digital-todigital conversion (DDC) and the development of a hardware-software complex (HSC) based on high-speed computing devices. As part of the project to create new high-tech equipment, the specialists of FSBEI HE “KSPEU” and JSC “ChEAZ” developed and created an experimental stand designed to verify and confirm the correctness of the selected structural and circuit solutions used in the design of a synchronous valve electric motor (SVEM) and rod control station borehole pumping unit (RC SBPU). The object of experimental research was the prototype and prototype electric drives of oil pumping units, as well as their components: SVEM and RC SBPU. The article discusses the ways of organizing the measuring and control channels of the measuring and information system of the experimental bench, which allows to study samples of synchronous valve motors and control stations of the sucker rod pump unit in the regimes that are as close as possible to real field conditions simulating the operation of the oil pumping unit of the sucker rod pump unit. Thus, in the experimental stand, analog, discrete and digital control and control channels are implemented.

At present, the pump setting depth of machine wells in Tahe Oilfield is universally too deep as the reservoir is buried deep, viscosity of heavy oil is high, and the producing energy weakened. This will increase the input of sucker rod, oil tube material and lead to enlarge suspension point load of pumping unit mule head and energy consumption. According to the problems, on the basis of the regularity of distribution of wellbore pressure field, viscosity field, temperature field, this paper puts forward a new matching lifting technology: moving down the point of blending and picking up the pump setting depth. Moving down the point of blending can reduce the producing energy loss and enforce the crude oil’s fluidity in the wellbore ,and picking up the pump depth can reduce the cost and energy consumption, Field test shows that after the new type matching lifting technology implement, test wells are normal in operation. The pump setting depth is partly picked up and pumping unit load decreases. The single well saves thin oil by more than 10%.

The article shows the types of complications that occur mainly in the fields of the Absheron archipelago in Azerbaijan and in the oil fields of the Azerbaijani sector of the Caspian Sea; the most common and frequent of them are the watering of the production of sucker rod pumping wells and the intensity of sand manifestations. It is noted that methods that prevent complications or reduce their negative impact are more appropriate than methods for their elimination. It is proposed to isolate formation water in flooded sucker-rod pumping oil wells using a universal hydrodynamic method; In this method, a liquid barrier should be created in front of the water in the formation, and not a solid barrier, and high-viscosity dead (non-gaseous) oil should be taken as a separating fluid, the specific gravity of which should be equal to the specific gravity of the formation water. The article uses the following five functions of multifunctional measures when carrying out various well survey methods: I. Pouring clean fluid into the annulus to increase the amount of fluid in the wellbore and reduce the concentration of sand particles in it. II. Without stopping the operation of the pumping unit, adding clean oil to the annulus with the help of a unit, raise its static level several meters higher. III. Determination of values of Pk, Po and G in rod deep well pumping wells producing viscous-plastic oil without stopping the operation of the pumping unit. IV. To determine the reservoir pressure in the simplest way, all well production is drained with a hose into the annulus. V. When removing the first lower curve by the method of two-sided restoration of curves without stopping the operation of the pumping unit VI. When applying the extraction method without changing the indicator diagrams S and n of water-cut oil wells. Thus, the use of multifunctional measures improves the performance of the considered wells and provides great economic benefits.

In order to calculate the working mode of a sucker-rod pump driven by the beam pumping unit and a jet pump during their simultaneous operation, pressure and temperature distribution along the wellbore from the bottom to the wellhead is determined for the real oil well 753-D "Dolynanaftogaz" Field Office. To calculate these parameters an improved methodology based on known Poettmann-Carpenter and Baxendel methods is used. As a result, the imperfection of these methods was eliminated, namely the assumption that pressure and temperature behavior along the wellbore is linear. This led to obtaining results which are up to 23% more accurate. In addition, using the algorithm for determining the density of perfect (ideal) liquid-gas mixture, the author has calculated the velocities of gas-water-oil and water-oil mixtures for a number of sections along the production tubing at different angles of the crank position in the beam pumping unit. The indicated values make it possible to determine the depth of the oilgas jet pump location in the well, and, consequently, the parameters at its input (pressure, temperature, velocity of the liquid-gas mixture, its density, etc.). Besides, the author studies the dependence which describes the behavior of the liquid-gas mixture density along the wellbore, as well as the relations between the density of the free oil gas, thevolumetric consumption gas content of the flow and the placement of the section under consideration. All of the above-mentioned algorithms were implemented using developed computer programs. The obtained results give a possibility to choose the location of the jet pump in the well which is the most advantageous one for ensuring maximum pressure reduction and the decrease in the stem load.

The issues of automation of technological processes are relevant for all industries. The article discusses the issues of automating the control of the operation of oil pumping units widely used in oil production using the TRACE MODE SCADA system from AdAstrA Research Group.
To control the operation of a sucker rod pump of an oil pumping unit, the use of dynamometers is widespread in world practice. Technically, it is easier to carry out a more generalized control of the operation of an oil pumping unit using a wattmetergram, which displays the dependence of the active power consumed by the drive on time or the position of the polished rod. The results of power measurements are transmitted via communication channels to the computer of the SCADA system. Further, preliminary processing of the results of the control of the wattmeter diagram and the calculation of parameters characterizing the operation of the oil pumping unit are performed.
At the stage of data preprocessing, noise filtering is performed using TRACE MODE tools that provide data exchange with MS Excel, MS Access, MS Visual Basic packages. The use of moving average, median filtering, and B-splines methods for this is considered. It is shown that cubic B-splines are an effective method of analytical description and graphical representation of experimental data, reducing the total mean square of the error. The use of splines in comparison with the polynomial approximation gives a slightly better approximation. The results of filtering and calculations by means of the SCADA system are displayed on the dispatcher’s monitor, archived, documented, etc. Thus, the related software products SCADA TRACE MODE and MS allow you to effectively implement complex data processing algorithms.

The function of displacements of external contour points of a friction pair hub that could provide minimization of stress state of a hub was determined on the basis of minimax criterion. The problem is to decrease stress state at that place where it is important. The rough friction surface model is used. To solve a problem of optimal design of friction unit the closed system of algebraic equations is constructed. Increase of serviceability of friction pair parts may be controlled by design-engineering methods, in particular by geometry of triboconjugation elements. Minimization of maximum circumferential stress on contact surface of friction unit is of great importance in the design stage for increasing the serviceability of friction pair. The obtained function of displacements of the hub’s external contour points provides the serviceability of friction pair elements. The calculation of friction pair for oil-well sucker-rod pumps is considered as an example.

Full textAbstract:
One of the major challenges with progressive cavity pump (PCP) applications in Australia is the production of highly concentrated solids. Large volumes of solids entering the production string cause both high torque issues and holes in tubing, resulting in lost production and the need for intervention with a flush-by unit or service rig. On account of these issues, it is reported that up to 40% of PCPs in the Australian coal seam gas (CSG) fields can be down at any given time. Coho Resources has introduced lined tubing as an engineered solution. The proprietary lining the tubing has a lower friction factor compared with conventional steel tubing, resulting in lower operational torque and reduced operating costs. The added lubricity from the lower friction coefficient in lined tubing allows solids to flow more freely to surface where they are captured and discarded from the system. Lined tubing allows producing companies to realise bottom-line operational savings in several ways. The largest of course is minimal downtime and reduced well service costs due to the elimination of our previous tubing related problems. With reduced work over costs, savings become visible very quickly. Rig costs, bottom hole pump, tubing and sucker rod replacement costs are all reduced. Application of lined tubing in CSG wells in Australia results in: • 15–25% less torque on the drive system, • An 70% increase in run times between workovers (lined tubing versus un-lined tubing), and • Compatibility with existing field equipment and handling methods.

Through the establishment of contact element simulated the contact between sucker rod and oil pipe. The deformation of sucker rods in oil pipe that caused by the screw pump rotor eccentricity has been researched by the application of transient dynamics analysis. Results show that screw pump rotor eccentricity is one of the reasons which cause rod and oil pipe contact resulting in partial abrasion. Deformation of the sucker rods caused by the rotor eccentricity is mainly concentrated on the bottom of rods, so in order to mitigate partial abrasion, rod centralizer arrangement at the bottom of rods should be strengthened, or change the connection mode between the sucker rod and screw pump rotor to eliminate the effect of the sucker rod deformation caused by rotor eccentric motion.

AbstractIn many oil reservoirs worldwide, the downhole pressure does not have the ability to lift the produced fluids to the surface. In order to produce these fluids, pumps are used to artificially lift the fluids; this method is referred to as artificial lift. More than seventy percent of all currently producing oil wells are being produced by artificial lift methods. One of the most applied artificial lift methods is sucker rod pump. Sucker rod pumps are considered a well-established technology in the oil and gas industry and thus are easy to apply, very common worldwide, and low in capital and operational costs. Many advancements in technology have been applied to improve sucker rod pumps performance, applicability range, and diagnostics. With these advancements, it is important to be able to constantly provide an updated review and guide to the utilization of the sucker rod pumps. This research provides an updated comprehensive review of sucker rod pumps components, diagnostics methods, mathematical models, and common failures experienced in the field and how to prevent and mitigate these failures. Based on the review conducted, a new classification of all the methods that can fall under the sucker rod pump technology based on newly introduced sucker rod pump methods in the industry has been introduced. Several field cases studies from wells worldwide are also discussed in this research to highlight some of the main features of sucker rod pumps. Finally, the advantages and limitations of sucker rod pumps are mentioned based on the updated review. The findings of this study can help increase the understanding of the different sucker rod pumps and provide a holistic view of the beam rod pump and its properties and modeling.

Summary When the oil price is low, cost optimization is vital, especially in mature oil fields. Reducing lifting costs by increasing the mean time between failure and the overall system efficiency helps to keep wells economical and increase the final recovery factor. A significant portion of artificially lifted wells currently use sucker rod pumping systems. Although its efficiency is in the upper range, there is still room for improvement compared with other artificial-lift systems. This paper presents the field-tested sucker rod antibuckling system (SRABS), which prevents buckling of the entire sucker rod string, achieved by a redesign of the standing valve, the advantageous use of the dynamic liquid level, and, on a case-by-case basis, application of a tension element. The system allows full buckling prevention and a reduction of the overall stresses in the sucker rod string. The resulting reduction in the number of well interventions combined with the higher system efficiency prolongs economic production in mature oil fields, even in times of low oil prices. The analysis of SRABS, using finite-element simulations, showed a significant increase in system efficiency. The SRABS performance and wear tests under large-scale conditions were performed at Montanuniversität Leoben’s Pump Test Facility and in the oil field. The results of intensive laboratory testing were used to optimize the pump-body geometry and improve the wear resistance by selecting optimal materials for the individual pump components. The ongoing field-test evaluation confirmed the theoretical approach and showed the benefits achieved by using SRABS. SRABS itself can be applied within every sucker rod pumping system; the installation is as convenient as a standard pump, and manufacturing costs are comparable with those of a standard pump. This paper shows improved performance of the SRABS pumping system compared with a standard sucker rod pump. SRABS is one of the first systems that prevents the sucker rod string from buckling without any additional equipment, such as sinker bars. Testing of SRABS has identified significant benefits compared with standard sucker rod pumps.

Summary The pump dynamometer card is a direct reflection of the operating conditions of the downhole pump, which is important for the diagnosis of sucker-rod pumping systems. In this paper, we propose a novel diagnostic method based on the estimation of the parameters from the polished-rod load vibration signal of sucker-rod pumping systems in a vertical well. In this study, we deduce a new analytic solution of the 1D wave equation of the sucker-rod string, which can be used for the predictive and diagnostic analyses. The relationship between the polished-rod load vibration and the pump equivalent impulse load based on the analytic solution is studied, and the diagnostic parameter estimating method is proposed. Therefore, the pump dynamometer card calculated method based on the surface dynamometer card is realized. This study shows that the method is efficient.

In the oil production process, the wear of friction pairs in sucker rod pumping installations will increase over time, which leads to the failure of the sucker rod pumping system. In order to study the effect of wear on the sucker rod pumping system, a wear model between the plunger and pump barrel was established. By analyzing the wear law, the wear volume and wear time of the pump barrel were calculated under abrasive wear. The forces of the sucker rod microunit were analyzed, and the wave equation of the sucker rod was established. Based on the given boundary and initial conditions, a mixed difference method was used to solve the equation. Taking the no. L2111 well of an oilfield as an example, the change curves of the wear volume and wear time with abrasive particle diameter were plotted, and the polished rod dynamometer card considering wear was predicted. The results showed that the increased clearance caused by wear will reduce the polished rod load on upstroke of the sucker rod pumping system, which could provide a theoretical basis for the next fault diagnosis.

Based on the field data, numerous failures of the downhole equipment of sucker rod pumping units occur, especially of the sucker rod strings. They are subject to corrosion, wear and alternating loads. The stress-strain state of the threaded connection elements is determined by the nature of the distribution of loads along the threads, which is uneven and depends on many factors. Despite this, the development of new designs of sucker rod connections and measures to improve the efficiency of operation and their research is an urgent task. In addition to the threaded connections of the sucker rods, there were a number of threadless designs that were not used in the fields, but they passed certain tests. The article presents these connection designs and discusses their advantages and disadvantages in comparison with standard threaded connections. Simulation modeling of a standard connection of sucker rods made it possible to investigate its stress-strain state and identify hazardous areas (stress concentrators). The stress-strain state of the threaded connection of the sucker rods has been investigated, the design of this connection has been improved and it has been established that, in comparison with the standard threaded connection of the sucker rods, the investigated has certain advantages. It was found that with an increase in the number of protrusions and depressions in a threaded joint, stresses decrease, which are concentrated in dangerous sections and along the contact planes. Convex contact planes also reduce stress, especially at the joint surface. Research has shown that the stresses generated in a threadless sucker rod joint are less than the stresses generated in a standard sucker rod and sleeve joint. Although the difference between these stresses is insignificant, attention should be paid to changing the geometric parameters of the threadless connection of the sucker rods, thereby reducing the maximum stresses.

For the development of lowand medium-rate wells, the most commonly used installations are sucker-rod pumps. The group of sucker-rod pumps connected to the same power supply system is installed on the wells of one oilfield. The work of a sucker-rod pump is cyclical. Obviously, there is a relationship between the maximum power consumption of a group of cycle drives and the performance of this group. Selecting such a strategy for reducing the maximum power consumption, in which there will be no significant performance reduction, is an urgent problem. In this article, theoretical approaches are formulated for constructing the simulation model of a sucker-rod pump group as a group of cycle drives with unequal cycles. Several group control strategies that reduce the maximum value of power consumption are considered.

The deep pump, mainly sucker-rod deep pumping method is widely applied in the onshore oil wells of Azerbaijan. Despite the fact that the deep-well sucker rod pumping method is widespread, its operation in sand-producing wells is accompanied by various complications. Since mechanical particles wearing the pump parts out, falling into the space between the plunger and the cylinder, either wedge the plunger inside the cylinder or increase the gap between them. To prevent the ingress of large particles of sand into the gap between the plunger and the cylinder of the deep sucker rod pump, a device for sand trapping has been developed. The sand-trapping device is installed within the well tubing strings on the rod string and prevents the big particles of the liquid in the pipes falling into the gap between the plunger and cylinder. As the plunger, the device is started via balanced head. Due to the equipment installation, the liquid injected from the pump undergoes pressure decrease and the conditions for deposition and accumulation of large particles are formed.
