FIELD: production of oil. SUBSTANCE: method involves measuring and maintaining predetermined pressure values at inlet of centrifugal pump and in pressure line and regulating rotational speed of pump drive; determining power coefficient by pump certificate characteristics measured on stand and by dependence recited in Specifications; plotting dependence of power coefficient value on current value of feeding; measuring active power and working current actually consumed by pump plant during operation in well; measuring pressure at well mouth and at pump inlet; determining actual value of pressure difference developed by pump and of power coefficient; determining current value of feed by pump corresponding to actual value of power coefficient in accordance with above mentioned dependence; setting pump feed value for level by regulating rotational speed of pump drive; maintaining predetermined pressure in pressure line by varying local resistance in pressure line of well mouth. EFFECT: increased efficiency of method and increased accuracy of method. 3 dwg
