Electrical submersible centrifugal pump units of the new generation for the operation of marginal and inactive wells with a high content of free gas and mechanical impurities

The paper is devoted to the development of innovative solutions for oil production in complicated conditions using submersible pumping systems. The conditions in which these systems should operate are described. A mathematical model used for computational fluid dynamic simulation is presented. Technical solutions, as well as their key features and advantages over existing systems are presented. The main conclusions are made.
