FIELD: oil and gas industry.
SUBSTANCE: current values of efficiency are brought to the nominal capacity, the technical condition is judged by the given values of efficiency, measures to optimize the pump operation mode are implemented when the values of efficiency in the current operating parameters reach the limit, while pulling pump out of operation and making its repairment are carried out when the values of efficiency innominal performance mode reach the limit.
EFFECT: increased efficiency of the pump operation, the extension of its inter-repair period, ensuring a timely overhaul repairment of the pump and reduction of the cost of maintaining formation pressure, increased efficiency of electrical centrifugal pump operation due to a more accurate assessment of the technical pump status, carried out by bringing the current values of efficiency to the nominal capacity and increasing the operational life of the pump before the next repair.
