Development of Pumping Equipment for Oil and Gas Production in Complicated Conditions

Abstract

The research is aimed at the development of new scientific principles for the creation of special pumping equipment for the extraction of oil and gas in complicated conditions. In many cases, the complicated operating conditions of the pump are determined by the high gas content and high content of mechanical impurities in the multiphase flow. In the course of scientific research, new methods of designing hydraulic machines were tested, including the use of additive technologies. In the study of labyrinth pumps, the issues were considered concerning the features of the operating process with increased rotor speed. New design of the rotor manufactured using additive technologies was discussed. It is shown that the rotor screw in a labyrinth pump can be replaced by a set of impellers, for example, by a set of centrifugal wheels or a set of axial wheels. New results concerning labyrinth pumps can give impetus to the development of research on hydraulic and gas turbines, as well as on heat engines. Some results of the works performed can be used to create robotics.
