Annotation:

The key problem, considered by the authors of the article, is the causes of premature failures of electric submersible centrifugal pumping units (ESCPU) operating in the oil fields of the Western Siberia. It has been established that the primary reason for equipment performance failures is the high content of free gas in the produced fluid. The complications arising in the course of pumping equipment operation in conditions of a high gas-oil ratio are analyzed. Particular attention is paid to a comparative analysis of the advantages and disadvantages of various methods for mitigating the gas impact used in the Bovanenkovskoye, Kharasaveyskoye, and Novoportovskoye fields. The presented results help to optimize the selection of technological solutions to improve the reliability of downhole equipment operation.
