The method of using a Sucker Rod Pump (SRP) is used if an oil well is no longer able to lift fluid from the bottom of the well to the surface by natural spray, or by using other methods such as a gas lift that does not meet the requirements. Sucker rod pump is one of the artificial lifting methods, where to lift the oil to the surface a pump is used to lift the oil to the surface using a pump with a rod chain. This pump is used for wells with low-medium viscosity, no sand problems, high GOR, straight wells and high fluid levels. The working principle of a sucker rod is a combination of motion between equipment on the surface and below the surface. And the expected end result using the artficial lift method is to maximize production so that it can meet predetermined production targets.</em></p>

Trapping Device

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.

The paper notes that as the depths of operated wells grow, the application of cable and pulley mechanisms becomes preferable as compared to the existing pumpjacks. A generalized theoretical analysis of the kinematics of cable and pulley drives is set forth. The authors present the general theoretical analysis of the kinematics of the above mechanisms, as well as the results of computer calculations based of the developed equations for a number of cases. Further analysis of the results showed that the crank mechanisms of a rope pulley have “smooth” kinematics. The research resulted in a proposed invention of the design of mast-type oil well sucker-rod pump drive with lower steel intensity and power consumption that would allow increasing the performance of sucker-rod pumps.The Purpose of this article consists in finding a utility model of a pump for the well rod in order to ensure the environmental safety of the equipment. That is achieved by lightening the metal structure of the pump with rotary stem and energy consumption is reduced. In the context of this problem, some calculations were performed in order to prove the system’s dependability. Based on the performed calculations it was established that the light structure can be used instead of the old heavy structure being its environmentally safe version. Experimental studies conducted by AzINMASH Research and Design Institute of Petroleum Engineering (Baku, Azerbaijan) indicate the feasibility of normal operation of sucker-rod pumps under the condition that n∙S = 54÷60 m/min. The authors examined the dependence between the peak output Q and the number of strokes n for various standard pumpjack sizes. The analysis of the parameters shown that the value of the product n∙S in the existing pumpjacks is below the recommendations based on experimental data, i.e. there is a tangible opportunity of increasing the productivity by extending the stroke of the rod hanger center, since well pump barrels may be as long as 6 to 7 meters. Estimates show that while studying the kinematics of long-stroke drives the changes in the length of the rope may be practically disregarded due to the displacement of the rope-to-pulley contact point. This simplifies the formulas that describe the kinematics of this type of long-stroke drives. Using the resulting formulas, comparative computer calculations for various cases were performed. It is shown that cable and pulley mechanisms have “softer” kinematics. The calculations confirmed the advisability of modification of the pump’s design that ensured reduced pollution of environment and energy savings. The future world will need renewable sources of energy, more power-efficient oil and gas production, minimal or zero pollution of the environment, thus the proposed solution appears to be of relevance. The authors propose a more productive design of sucker-rod pump that is easy to install and maintain at oil and gas production facilities. That can be achieved based on the calculations mentioned above.

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 and while additional installation of the oil-gas jet pump above its dynamic level. For this purpose, commonly known methods of Poettman-Carpenter and Baksendel were used. In addition, the equations of high-pressure and low-pressure oil-gas jet pumps were obtained for the case, when the working stream of the jet pump is a gas-oil production mixture and the injected stream is a gas from the annulus of the well. The values which are included in the resulting equations are interrelated and can only be found in a certain sequence. Therefore, a special methodology has been developed for the practical usage of these equations in order to calculate the working parameters of a jet pump based on the given independent working parameters of the oil well. Using this methodology, which was implemented in computer programs, many operating parameters were calculated both for the well and for the jet pump itself (pressures, densities of working, injected and mixed flows, flow velocities and other parameters in control sections). According to the results of calculations, graphs were built that indicate a number of regularities during the oil well operation with such a jet pump. The main result of the performed research is a recommendation list on the choice of the oil-gas jet pump location inside the selected oil well and generalization of the principles for choosing the perfect location of such ejectors for other wells. The novelty of the proposed study lays in a systematic approach to rod pump and our patented ejector pump operation in the oil and chrome plating of pump parts. The result of scientific research is a sound method of determining the rational location of the ejector in the oil well and the calculation of its geometry, which will provide a complete selection of petroleum gas released into the annulus of the oil well. To ensure reliable operation of jet and plunger pumps in oil wells, it is proposed to use reinforcement of parts (bushings, plungers, rods, etc.) by electrochemical chromium plating in a flowing electrolyte. This has significantly increased the wear resistance and corrosion resistance of the operational surfaces of these parts and, accordingly, the service life of the pumps. Such measures will contribute to oil production intensification from wells and improve the environmental condition of oil fields.

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.
