Abstract:

Drilling construction quality is closely related with drilling engineering design level, however, drilling engineering design includes multi different professional fields such as geology, reservoir and drilling engineering and so on, and optimization design needs people’s cooperative work from different specialties and sections. Today drilling engineering design is usually completed by relevant staffs in isolation, and then drilling engineering planning report is generated by collection. In this process of design, there are lots of problems, such as lack of formation interaction, long design period, and inadequate capability to meet the high efficiency of optimization requirements. In this paper the model of drilling engineering cooperative design based on workflow is put forward, and by using computer workflow technology, planning automatic design workflow and providing cooperative work environment for people in different specialties and fields, it can satisfy the need for information sharing during design process, improve design efficiency, and provide support for drilling optimization design. The multi-user cooperative model and workflow management model of drilling engineering design is detailed in this paper.

Abstract:

Auger drilling is widely employed in pile foundation engineering and sampling test for geological sciences, and is even considered as one of the idealest methods for space sampling. However, in practice, drilling parameters are usually determined by experience which might cause unnecessary accidents as a result of transportation blocking of chips. To achieve smooth chips transportation, the existed critical speed models are firstly analyzed and summarized in this paper followed by the main introduction of the proposed new model of critical drilling parameters. The influence of rotational speed and vertical feeding rate on the actual trajectory of chips transportation as well as the selection of critical models for different applied drilling fields are subsequently investigated and discussed herein. Analyses indicate that the critical models of overall combined chips and chips divided into inner and outer layer are more reliable, vertical feeding rate and rotational speed should be taken into account simultaneously. The analyses on the actual trajectory of chips transportation are helpful to understand the motion state of chips. To achieve safe and efficient drilling production, suggested drilling parameters should be provided by manufacturers according to the solving models mentioned in this paper and the specific drilling fields.

Abstract:

The existing computer technology is used to conduct an in-depth study and analysis of drilling waste treatment, and the results are analyzed by computer simulation optimization algorithms. Based on the system theory, we define the research system, combine the unique characteristics of the technological innovation mechanism of drilling waste treatment, and use the internal and external factors affecting the technological innovation dynamics of drilling waste treatment, such as drilling waste treatment capacity, from the current actual situation. On this basis, factor analysis is used to analyze the factors affecting technological innovation dynamics from both internal and external aspects of the system, establish a system model of technological innovation dynamics of drilling waste disposal, and give the initial values of the simulation model. This will reduce the pollution of the environment and enhance the competitiveness of enterprises. Drilling waste treatment technology is getting increased attention, but at this stage, there is no suitable technology innovation mechanism for drilling waste treatment. Through the simulation trend chart obtained by sensitivity analysis, the key factors in the system are found, and the innovation power mechanism of drilling waste treatment technology is constructed, which provides a basis for the formulation of enterprise technological innovation strategies and the development of technological innovation activities. Research on the dynamic mechanism of drilling waste treatment technology innovation explores a waste treatment mechanism suitable for the drilling industry, so as to promote the steady development of the drilling industry and at the same time provide theoretical support for the treatment of drilling engineering waste.

Abstract:

Drilling engineering is important for development of underground resources. There are many potential risks in the process of drilling engineering. If the drilling safety is not effectively managed, it will lead to great loss. In order to predicate and prevent safety accidents, a safety evaluation index system is established and an AHP-ACE method is proposed. 23 groups of original drilling data are collected from a block of Xinjiang oil field, and the safety levels are quantitatively analyzed by characteristic values. First, the AHP method is applied to relate direct observation variables to potential variables by calculating weight and determining membership function of each index. Second, three potential variables are chosen as the input of the ACE model and a training set containing 17 groups of data is used to establish the mathematical relationship between the potential variables and drilling safety value. Finally, the validity of the proposed model is examined by matching it to the other 6 groups of data. This study provides a new and effective way to quantitatively evaluate the safety of drilling engineering.

Abstract:

In geotechnical engineering and geological survey, the stratum structure and its corresponding physical and mechanical properties are the most concerned. The stratum structure not only affects the safety of the project but also plays a decisive role in the construction method and construction sequence. In this paper, a new type of stratum geological interface recognition system is adopted, and an R-20 rotary drilling rig is used to conduct on-site drilling experiments for a granite site with no ventilation. The research results show that the system can monitor and record the main parameters (axial pressure, drilling rate, rotation speed, flushing fluid pressure, and torque) of the drilling rig during the drilling process. The comparative analysis of monitoring data and on-site survey results shows that different drilling parameters have different sensitivities to changes in the formation structure. According to the prediction accuracy, the ranking from high to low is drilling rate, axial pressure, torque, rotation speed, and flushing fluid pressure. In drilling engineering, by observing the change law of drilling rig parameters, not only can the position of the special rock mass interlayer be predicted, but also the stratum structure and strength can be identified, and the prediction formula is also given. Based on the established drilling specific energy formula, the energy analysis method is used to predict the formation structure and compressive strength, and the corresponding prediction formula is given. The research results show that, compared with the single drilling parameter prediction method, the rock-soil structure and strength identification method based on energy theory has higher prediction accuracy and can meet engineering needs.

Abstract:

Rock burst is a common mine disaster often accompanied with casualties and property damage. In order to effectively predict and prevent the rock burst occurrence, an effective and accurate method for predicting rock burst is necessary. This paper first establishes the relationship between the drilling cuttings and the releasable elastic deformation energy. However, the traditional drilling cutting method has the defect that the drilling depth cannot reach the stress concentration area and the drilling cuttings cannot accurately reflect the internal stress variation in the deep part of coal body. So, an improved drill cutting method is presented to make up for these defects. Finally, the combined monitoring method based on the improved drilling cutting method and the microseismic monitoring method is established. It not only overcomes the limitations of a single prediction method but also effectively utilizes the advantages of improved drilling cutting method and the microseismic monitoring method. And this combined monitoring method is applied to the No. 3302 coalface of Xingcun Coal Mine. The obtained results indicate that the combined monitoring method can improve the prediction capabilities of the rock burst and provide novel insights for preventing the rock burst occurrence.

Abstract:

Well engineers face ever increasing technical challenge of drilling in complex environments and the use of Managed Pressure Drilling(MPD) techniques to control annular pressure for improved drilling performance in the oil industry has growing interest[1-4]. Understanding hole cleaning and controlling annular pressure in this complex environment is becoming increasingly important for a range of applications. The Virtual Well Engineer[VWE] has been identified as the engineering tool to address these issues in order to deliver a successful MPD operation. The VWE is the product name for a suite of well planning , monitoring and simulation packages with focus on Managed Pressure Drilling includng underbalanced drilling that allows the well engineering team to interact with virtual reality. Recent works initiated by the Well Engineering Group at The Robert Gordon University have extended the knowledge of multiphase flow in a drilling annulus through the tracking of the transient multiphase flow pattern prevailing and effects on hole cleaning , the pressure profiles and identification of hot spots in concentric and eccentric annular sections . The mechanistic models developed at RGU form the core algorithms for the VWE. This paper presents the architecture and functional capabilities of the VWE – HydraulicsDTS™ , which is used in simulating well operations.

Abstract:

Based on the introduction of the working principles of various automatic vertical drilling systems (VDS), the latter are divided into rotary push type and sliding push type. Then the technical advantages and applicable scope of various types of drilling tools are analysed. Combined with the latest domestic application progress and typical case analysis of the vertical drilling system, the future development direction of the vertical drilling technology is predicted. The results show that, the existing vertical drilling technology can better meet the technical needs of rapid drilling in the middle-deep sections with high steep angles. While the stability of wireless information transmission and wear resistance of the push pad still need further improvement. The new type of vertical drilling system that is miniaturized (suitable for small boreholes) and resistant to high temperature and high pressure is in urgent need to fill the gaps in the market segment. Domestic independent vertical drilling systems have made great progress, some even surpass foreign products in key indicators such as temperature resistance, in addition to achieving the technical goal of anti-inclination successfully. Finally, based on the engineering geological conditions of Shunbei 11 well, feasible vertical drilling tools were recommended and achieved engineering goal finally. The research results can provide support for the drilling company to optimize the vertical drilling system based on engineering-geological conditions.

Abstract:

The derrick of a drilling ship is a kind of dynamic ocean derrick which is often applied to drilling operations for ocean engineering. Comparing with land rig derrick, the operating environment of drilling derrick is more complicated with not only the regular functions of static force but also the dynamic loads induced by wind, wave and current. Therefore, this paper takes a drilling derrick as example to make clear of the dynamic characteristics of the drilling derrick under the action of dynamic loads from outside environment with the finite element software ANSYS as tool to accomplish the modal analysis of the drilling derrick. According to the natural frequency and the vibration mode of the drilling derrick after modal analysis, the deformation response and the weak parts of the drilling derrick under different motivation can be predicted, and some improving suggestions can also be illustrated as well. This paper completed the dynamic analysis of the drilling derrick by modal analysis, and moreover, the displacement response and the stress of the drilling derrick varied with time can also be obtained. As consequence, the conclusion can be taken as reference for design of the drilling derrick, safety application and life sustainment.

Abstract:

Due to the repeated cracking caused by the adsorption of cuttings on the surface of drilling bits and BHA during drilling operation, the rate of penetration (ROP) could reduce remarkably. The anti-balling additive for drilling fluids (ABA) could eliminate the adsorption effect of cuttings, and increase ROP significantly. In this paper, the mechanism of eliminating the adsorption effect of cuttings was investigated in details. The results indicate that ABA can form multilayer chemical and physical adsorption on the surface of drill bits and BHA in the form of oriented adsorption of organic phosphine, which is of great importance to the design of drilling fluid system and field operation to raise ROP.

Abstract:

The widespread utilization of engineering ceramics has been limited by fracture in the machining process. A technical basis for avoiding fracture requires a fundamental understanding of the fracture mechanisms in machining. The present paper is intended to discuss the fracture mechanisms during the vibration drilling of holes in engineering ceramics. In this paper, the stress distribution during the vibration drilling of holes in ceramics has been analysed. The results show that, in the terminal period of vibration drilling, the stress on the periphery of the hole exit is at its maximum. It is the main reason for fracture at the exit of holes in engineering ceramics. The condition for no fracture at the exit is given, and an effective method is proposed to avoid such fracture.

Abstract:

In industry, high-density packaging technology is an unavoidable requirement. Therefore, the drilling hole of printed circuit boards, PCB, requires being much smaller, even down to 0.1 mm or less. Drill fractures are frequently found in the micro drilling process due to the micro scale, hole-location errors, reaming. In all micro drilling failure cases, there existed a large vibration or instability is frequently found because of the insufficient rigidity of supports for a system with a super-high spinning speed. To improve the drilling quality and avoid drill breakage, the effects of support stiffness and high rotational speed of the vibration in the micro drilling process must be studied. Most investigations on the vibration of micro drilling are focused on only drill self-structure. However, in an actual engineering application, the micro drill must be attached in a bearing spindle system. This study considers the vibration of a micro drill with a gas bearing spindle. Hence, it includes the effects of the rotation speed, air pressure, and clearance of gas bearing on the vibration in a micro drilling process. After constructing the governing equations of the system, the numerical analysis by the Fortran programming is performed to solve for the frequency and amplitude response of the spindle system over time. The results indicated that the spindle with the gas bearings effect increased the vibration in the micro-drilling process.

Abstract:

The article is devoted to the effective analysis of trench and trenchless pipeline laying technologies. In the course of the work, an analytical review of pipeline assembly was performed, the main technological parameters, the scope of each method, and their advantages and disadvantages were determined. List of considered pipeline laying methods: trenching, horizontal directional drilling, mechanical puncture, hydraulic puncture, microtunneling and punching. The article analyzes the classical trench method and the most widely used trenchless ones: horizontal directional drilling; mechanical puncture; hydraulic puncture; microtunneling; punching. Each of these methods has several advantages and disadvantages. The choice of the optimal method of laying the pipeline depends on many factors: the physical and mechanical properties of soils and hydrogeological conditions, the length and diameter of the pipeline, the presence of other communications, buildings and structures, as well as the budget that customers have. Work time is the last deciding factor. Based on the results of the analysis of pipeline laying technologies and expert survey of construction industry experts, the cost table of each method was compiled, outlining the main characteristics of the technology: length of pipeline, speed of work, scope, cost, and the advantages and disadvantages of each of the considered methods. The conclusions about the use of each of the pipeline laying methods were made. Each of the methods has its advantages and disadvantages, so to choose the method of work it is necessary to conduct a comprehensive assessment of technological parameters, cost, scope and timing of work. The cost of lay-ing the pipeline consists of the following factors: conducting research; selection of diameter and determination of pipeline length; choice of laying method and equipment necessary for the works; selection of equipment, shut-off and control equipment and other materials arranged on the pipeline; terms of performance of works. Taking into account these factors, an estimate is made, which determines the cost of installation of a particular pipeline. After the analysis, we can conclude that among the methods of trenchless laying of pipelines can be identi-fied horizontally directional drilling, it is this method of laying the pipeline will be appropriate to use for our region. The drilling technique allows to carry out pipelines under obstacles, to pull long segments of networks, to repair site damage. This method is universal and can be used in almost any environment. Keywords: trenches, horizontal directional drilling, mechanical puncture, hydraulic piercing, microtunnelling, punching, pipeline.

Abstract:

An experimental study was carried out to investigate the force in drilling of engineering ceramic with a brazed diamond tool. The drilling forces and protrusion heights of diamond grains were measured. The results showed that the variation of cutting forces, increasing with the cutting time, was divided into three phases for a drilled hole. For each phase, the variation of cutting forces was different. The drilling forces also increased with the numbers of drilled holes due to the wear of diamond grits. The distance values of the cutting force between the end of first phase and the end of second phase approximately kept constant.

Abstract:

Reliable estimates of bottom‐hole temperature (BHT) in oil wells are of considerable interest in reservoir engineering problems as well as in geothermal research. Because BHT measurements are usually made soon after drilling, true formation temperature can be obtained only by correcting for the effects of drilling disturbances. The magnitude of drilling disturbance depends upon duration of drilling, time elapsed after stoppage of drilling, well characteristics, thermal properties of drilling fluid, and the nature of heat exchange between the well and the formation.

Abstract:

Engineering ceramics are increasingly extensively applied in the aerospace, vehicle, armor protection and other fields due to their excellent performances such as high compression strength, high hardness, low density and high protection performance. However, engineering ceramics are typical difficult-to-machine materials, especially in the hole machining under constant feed rate, which limits the promotion and application. In this study, by combining a specially developed novel thin-wall diamond trepanning bit with a low-frequency axial vibration machining, the hole machining process for the constant feed rate of Al2O3 engineering ceramics was experimentally studied and the influence of the low-frequency axial vibration process on the axial drilling force, hole-wall surface roughness and edge chipping size of holes machined was analyzed. The results showed that the low-frequency axial vibration machining obtained a lower axial drilling force and a smaller edge chipping size compared to the traditional drilling process. Moreover, both the axial drilling force and the edge chipping size declined markedly with the rise in amplitude. However, the hole-wall surface roughness presented a rising trend due to the hammering effect of vibration. The process technology proposed in this article realizes the hole machining for a constant feed rate of Al2O3 engineering ceramics and provides a reference for the engineering lot-size hole machining of engineering ceramics.
