FIELD: oil and gas industry.
SUBSTANCE: invention is related to the field of oil recovery by means of electrical submersible pumps. The feeding system contains a well casing and is used for fluid pumping from the producing zone to the surface. The well casing is equipped with a pump P located in the producing zone, a driving head located at the surface and a sucker rod string connecting the pump P and the driving head. Transmission T is connected between the pump P and the driving head at the sucker rod string. Fluid pumped from the producing zone is transferred through pipeline 32 passing through the transmission T lengthwise, in independent way.
EFFECT: invention is oriented towards optimal use of available space inside the well when the pump P created pressure sufficient for the formation fluid rising to the surface.
