IMPROVING THE PERFORMANCE OF PUMPS IN OIL FIELDS

Abstract

In this article, the main task of the work is to increase the amount of oil recovery from wells by studying the factors affecting the performance of deep well pumps due to changes in the composition of the raw materials of oil wells and methods for eliminating them. The increased level of hydration of the productive layers in oil fields creates difficulties in the process of mechanical extraction, collection and preparation of commercial oil. The opposite of such difficulties is the formation of viscous water-oil emulsions, which have a large value. Many scientists have conducted scientific work on the problems of improving the effectiveness of the operation of rod deep well pumps and their impact on the performance of pumps. Stable emulsions lead to breakage of rods when using a submersible pump (submersible pumps), breakage of electrical components in a centrifugal electric pump (CEP), and premature repair of SEM (submersible electric motors). Due to the incomplete filling of the chamber of the submersible pump with liquid and the increase in hydraulic resistance in the working parts of the centrifugal electric pump under the influence of the tensile stress applied to the rod, the daily transmission rate decreases by 2 times. The factors that negatively affect the performance of the use of submersible pumps in oil production, namely the release of dissolved gases in the oil, sand particles, heavy hydrocarbons in the wellbore and the working parts of the pump, and their consequences are presented.
