DEVELOPMENT OF OİL PRODUCTİON IMPROVEMENT TECHNOLOGY

It is important to conduct research without storing wells. Prior to this study, the wells will be shut down to explore the wells and additional work will be done for the survey. The research work itself took 15-20 days, using this research to determine the necessary parameters for the joint operation of the reservoir in a short time. In solving engineering problems, the force often applied to the system is to determine its reaction. In such cases, the correct answer to the question can be obtained on the basis of theoretical calculations. However, this is not always possible, and in some cases, instead of a mathematical model of the object under study, research is conducted to find a similar one. An electrical circuit can be thought of as a similar model of the mechanical oscillations of a solid. Therefore, by studying the motion of an electric charge in an electric circuit, it is possible to apply the oscillations of a mechanical system and the distribution of pressure in a porous medium by studying the distribution of heat in an object. If the final results of the two events are similar, then the modeling can be performed. The formation is considered as a working machine to determine the similarity of the drainage zone of the oil and gas well. In this case, the fluid system is lifted by lifting pipes to a certain height with formation pressure and the production of the well is ensured. As a result of the research, it was found that the mode of operation of the drainage zones of the strata in the wells is close to the mode of operation of centrifugal electric pumps. Keywords: debit, formation pressure, gas flow rate, drainage zone of the well, hydraulic characteristics of discharge line, bottomhole pressure, stress on discharge line of the pump.

ANALYSIS OF THE INFLUENCE OF THE CHECK VALVE FORM ON THE FUEL-SUPPLY PROCESS IN THE DISTRIBUTION TYPE PUMPS

The stability of the values of cyclic feeds and the angle of the actual beginning of the fuel supply largely depends on the presence of the injection valve of the fuel pump section and its design features. The valve must reliably separate the discharge line from the pre-plunger space and, within certain limits, ensure the residual pressure in the discharge line between cycles. However, the installation of the valve causes a repeated reflection from the valve of the pressure impulses, that follow from the nozzle and leads to the appearance of additional injections or a sluggish fit of the needle on the sprayer seat. In order to eliminate negative consequences, double-acting injection valves are installed on distribution-type pumps, in which the pressure impulses are extinguished by transferring fuel through an additional non-return valve. The use of double-acting valves with non-return valves on distribution-type pumps ensures reliable unloading of the discharge pipe from the cut-off cavity. One of the main purposes of a non-return valve is to provide the necessary hydraulic density of the coupling pressure valve - non-return valve. Serial pumps are equipped with cross-shaped and round-shaped check valves in cross-section, which are designed to provide the same hydraulic tightness of the coupling pressure valve - non-return valve. In the course of research, the results of which are presented in the work, it was revealed that they have different sealing characteristics. In parallel, the characteristics of a triangular and square check valve in cross section were investigated. As a result of research, it was found that square valves have the best sealing characteristics. In the course of the research, it was also revealed that serial check valves of cruciform and round shapes do not provide their functional interchangeability, since they have different abilities to ensure hydraulic tightness of the interface with the discharge valve - non-return valve. Square-shaped check valves in cross-section are more technological to manufacture.
