Abstract
This article is devoted to researching ways to increase the reliability, strength, and overall service life of Electric Submersible Centrifugal Pump (ESCP) Units. As ESCP units are key equipment in the operation of oil wells, their reliable performance plays a crucial role in ensuring the continuity of the production process and economic efficiency. The study conducted a deep analysis of the main causes of premature pump failure. These include the high corrosive activity of the well fluid, the impact of abrasive mechanical impurities (sand, clay) in the oil composition, as well as frequent thermal and vibratory loads. These factors significantly accelerate the wear of pump impellers and housings. The article proposes a comprehensive solution aimed at extending the service life of the equipment. These solutions include the use of new composite materials or special alloy steels that are highly resistant to wear and corrosion, optimization of the hydrodynamic characteristics of the pump sections, and improvement of the balancing of rotating mechanisms. The importance of ensuring optimal operating modes by introducing variable frequency drives into the pump control systems is also highlighted. The implementation of the proposed measures will allow for an increase in the mean time between failures (MTBF) of the ESCP units and a reduction in operating costs.
