SYSTEM FOR STABILIZING THE DYNAMIC LEVEL OF LIQUID IN A WELL EQUIPPED WITH AN ELECTRIC SUBMERSIBLE PUMP Russian patent published in 2023 - IPC F04B49/02 

FIELD: oil production.

SUBSTANCE: invention can be used to stabilize the dynamic level of fluid in a well equipped with an electric submersible pump (ESP). It is intended to ensure the uninterrupted operation of wells in an automated way. The system for stabilizing the dynamic level of liquid in a well equipped with an electric centrifugal pump includes an automatic control system, a dynamic level detection system and an electrically controlled valve. The automatic control system consists of an ESP control station with an electrically controlled valve control unit and a valve control controller. The dynamic level detection system, according to the invention, is equipped with three pressure sensors: an intake pressure sensor as part of the ESP thermomanometric system, a pressure sensor located in the valve control controller, and an annulus pressure sensor located at the wellhead. The electrically controlled valve includes a cable entry, an electronics unit, a mechanics unit, and a liquid choke unit.

EFFECT: improving the reliability of the ESP and ensuring the continuity of its operation.
