Abstract

The tendencies of development of well borehole pumps serving for exploitation of oil fields are analyzed. The desire to optimize the process of mixing flows has led to the emergence of numerous designs of jet pumps, in which instead of direct-current twisted streams are used. Creation of circulating flows in the flow part of the jet pump contributes to the alignment of the velocities of the coaxial flows, intensifies the process of exchange of energies in the liquid, and increases the efficiency of the mixing process. The combination of direct and circulating flow of flow allows us to improve the technical characteristics of jet pumps up to 30%. The geometrical dimensions and the mutual orientation of the elements of the flow part of the jet pump have a decisive influence on the energy efficiency of the implementation of ejection technologies. Optimization of the geometric dimensions and orientation of the components of the jet pump necessitates multifactorial experimental studies, which, in addition to the design factors, should also take into account the operating regime of the ejection system in the well. The task of optimizing the design and regime parameters of a well eccentric system can be solved by simulating the working process of the jet pump using modern software complexes Solid Works and ANSYS, which provide the necessary accuracy of the calculation operations. The efficiency of the ejection system also depends on the depth of its installation in the well. Determining the optimum depth of installation of the ejection system in the well provides the use of iterative methods of calculation with the use of appropriate computer programs (for example, Matchad). The development of the hydrosploded operation of oil wells is characterized by the emergence of a tendency for a joint arrangement of the ejection system and traditional types of deep pumping equipment. In the design of the combined oil extraction system, the jet pump creates a low pressure zone on the wellbore and intensifies the flow of hydrocarbons from the productive horizon, while the traditional downhole pump transports them to the surface. The presence in the well of an additional (jet) pump optimizes the conditions of use of the main pump, which improves the energy characteristics of the bottom-set layout and increases the efficiency of oil production. Analysis of the application of hybrid ejection technologies indicates the prospect of this direction of development of oil and gas equipment.
