Abstract

The development trends of hydraulic jet pumps used for the oil-fields exploitation are analyzed. The ambition
to 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 pumps up to 30%. The dimensions and the mutual orientation of the elements of the pump wet end have a decisive influence on the energy efficiency of the ejection technologies implementation. The optimization of 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 working mode of the ejection system in the well. The task of optimizing the design and mode parameters of a well ejection system can be solved by simulating the work 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 location in the well. Determining the optimum depth of installation of the ejection system in the well presupposes the use of iterative calculation methods with the aid of appropriate computer programmes (for example, Matchad). The development of the hydro-jet operation of oil wells is characterized by the tendency of a joint arrangement of the ejection system and traditional types of downhole pumping equipment. In the design of the combined oil-producing system the jet pump creates a low pressure zone in the bottom and intensifies the inflow of
hydrocarbons from the production horizon, while the traditional downhole pump transports them to the surface. The presence of an additional (jet) pump in the well optimizes the conditions of the main pump use. It improves the energy characteristics of the bottom-hole assembly and increases the efficiency of oil production. The analysis of the hybrid ejection technologies application indicates the prospects of this trend of oil and gas equipment.
