DOWNHOLE ELECTRIC CENTRIFUGAL PUMP CONTROL DEVICE Russian patent published in 2024 - IPC F04D15/02 

FIELD: oil production.

SUBSTANCE: invention can be used to stabilize pressure at the intake of an electric centrifugal pump (ECP) in operating conditions of marginal wells. It is intended for providing uninterrupted operation of marginal wells by automated method. Technical problem of invention is creation of device for pressure stabilization at inlet of electric centrifugal pump. Device for stabilizing pressure at the inlet of an electric centrifugal pump, equipped with a liquid bypass mechanism, includes an automatic control system made in the form of a command supply device, and a dynamic level determining system made in the form of level determining devices installed at the upper and lower boundaries of the dynamic level. At that, each device for determination of level contains holes for fluid drainage and filling. Command feed device is integrated into the control station located on the surface and represents a computational and control cluster with a current distribution system.

EFFECT: electric centrifugal pump higher reliability and continuous operation.
