Abstract:

The scope of downhole ejection systems is limited by the low value of the efficiency of the jet pump, the value of which usually does not exceed 35 %. Significant energy losses when mixing flows are the reason for the low efficiency of the jet pump. The energy performance of the downhole ejection system can be increased by creating swirling vortex circulating currents in the flow part of the jet pump. This optimizes the nature of the flow mixing and increases the energy performance of the jet pump. In the process of studying the structures, features of the working process and usage experience

Insufficient energy performance of ejection equipment and a high probability of non-operating modes of its operation reduce the efficiency of downhole jet pumps. The method of determining the design and operating parameters of the well ejection system, which provide the maximum efficiency of the jet pump, is presented. The proposed algorithm for determining the optimal values of the geometric dimensions of the flowing part of the jet pump involves the construction of a series of pressure characteristics for different values of its geometric parameter, the calculation of the efficiency and the

During oil fields operation, gas is extracted along with oil. In this article it is suggested to use jet pumps for utilization of the associated oil gas, burning of which causes environmental degradation and poses a potential threat to the human body. In order to determine the possibility of simultaneous application of a sucker-rod pump, which is driven by a rocking machine, and a jet pump (ejector) in the oil well, it is necessary to estimate the distribution of pressure along the borehole from the bottomhole to the mouth for two cases: when the well is operated only be the sucker-rod pump an

Abstract:

The development trends of hydraulic jet pumps used for the oil-fields exploitation are analyzed. The ambitionto optimize the process of mixing flows has led to the emergence of numerous designs of jet pumps, in which swirling flows are used instead of direct flows. The creation of circulation flows in the pump wet end promotes alignment of coaxial flows velocities, intensifies the process of energies exchange in the liquid, and increases the efficiency of the mixing process. The combination of direct and circulation flows gives a possibility to improve the technical characteristics of jet pump

Abstract The article proposes a jet pump for the bottom hole assembly. The developed supra-bit jet pump provides an additional circulation loop of the drilling fluid above the bottom of the well, which creates a local depression of the formation. In addition, the jet pump grinds the sludge injected from the annular space in the mixing chamber and feeds it to the bridging machine, which is included in the assembly, for temporary isolation of the productive formation. Isolation of the productive formation is necessary to prevent the flow of formation fluids into the wellbore when underbalanced.

In the Oil and Gas industry, installing pipe loops is a well-known hydraulic practice to increase oil pipeline capacities. Nevertheless, pipe loops could promote an unfavorable phenomenon known as fouling. That means that in a heavy oil-water mixture gathering system with low flow velocities, an oil-water stratified flow pattern will appear. In consequence, due to high viscosity, the oil stick on the pipe, causing a reduction of the effective diameter, reducing handled fluids production, and increasing energy consumption. As jet pumps increase total handled flow, increase the fluid velocities,

Abstract:

The purpose of this analysis is to evaluate the structural integrity of the jet pump assembly of a BWR during the performance of its operational and safety functions. The natural frequencies and vibration modes of the jet pump assembly immersed in water were determined. It was observed that the fourth mode shape was torsional, and its associated resonance frequency was 41.82 Hz. Also, the vibration induced by the flow in the leakage of the slip joint was analyzed with an axisymmetric model. The gap of the slip joint was varied from 0.2 mm until 0.65bmm. A gap between 0.6 and 0.64, would cause

Abstract:

This paper presented an implementation of entropy generation analysis in the main flow field of a water jet pump via the CFD method. This study aimed to identify the inefficient location of energy conversion and to analyse entropy generation sources in each region of the water jet pump. The 2D-axisymmetric model and realisable k-ε (RKE) turbulence model at steady-state conditions were performed to validate jet pump performance and to assess the entropy generation. Likewise, the effects of the projection ratio and throat-aspect ratio as independent parameters were investigated. As a result, the

The scheme of theoretical analysis of the influence of rotational motion on the working process of the near-bit jet pump is chosen, the methods of its realization and limits of use are determined. On the basis of the potential flows theory with the application of elementary hydrodynamic functions of a complex variable, basics for the development of analytical models of the near-bit ejector pump operation for conditions of its rotation in a well have been worked out. Components of a mixed flow are modeled as functions of the vortex flow and parallel jet flow. Application of certain hydrodynamic

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

Abstract:

Although significant advances have been made in tandem-blade technology for axial and centrifugal compressors, little attention has been paid to its application in centrifugal pumps. In this study, we propose a new tandem-blade design method for improving inner flow characteristics and overall performance of a centrifugal pump. With the SST k − ω turbulence model, three-dimensional turbulent flow fields in the centrifugal pump with tandem blades are simulated and analyzed. The effects of tandem blades on the inner flow and performance characteristics of the centrifugal pump are investigated. T

Ultra-high-pressure-jet-assisted drilling is a main technique for improving the rate of penetration in well drilling. In this paper, a novel down-hole pump with hydro-automatic reversing valve was designed and explained. The equipment is a kind of hydraulic piston pump in which the reversing valve, the core component of the pump, is a five-way, two-position control valve. With the explanation of the working principle, it is understood that the down-hole pump has simple operating principle. According to schematics of the assembly drawing, also it is known that the actuations of pistons, check v

Abstract:

For shale gas wells, in the initial production stage, the liquid production is large, and the lifting process is needed to assist the drainage. However, for gas wells, especially shale gas wells, the ultimate purpose is different from that of oil wells, and the current design method of pumping depth cannot meet the field requirements. Starting from the production characteristics of liquid-producing gas wells, this paper analyzed the gas well productivity, wellbore pressure distribution and critical liquid-carrying flow, and adopted the node analysis method to propose a design method for the pu

Abstract:

Hydroelectric power stations generate turbulent flow conditions, which represent a potentially significant hydraulic stressor to fish passing through the turbine system. A test facility has been developed using two randomly actuated synthetic jet arrays (RASJAs) of 25 independent submersible pumps to generate a turbulent flow field for biological dose-response testing. The novel elements of this approach include the ability to control the exposure duration within a test volume due to low mean flow velocity as well as the capacity to scale the turbulence levels as a function of pump capacity.
