FIELD: oil and gas industry.
SUBSTANCE: system includes several tubular elements located in each other with the channels directing the fluid flows from different formations of the well to different channels of tubular elements fixed in the casing pipe by means of packers. Channels are equipped with spool-type gates with control electric drives providing separate movement of fluid flows from different formations through different channels by means of a processor and a fluid parameter measurement sensor installed in each channel and functionally connected to the automatic control processor of the valve in compliance with the information received from the sensor, and further selective mixing of flows in the area of the casing pipe. Tubular elements are fixed in the casing pipe with upper packer, and at their inlets, they are connected to the coupling directing different flows via different channels from different formations, which is connected via a central channel by means of the shank to the extracting device of the product from bottom formation of the well, which is fixed in the casing pipe with lower packer. Unit of separate supply and accounting is connected via a branch pipe to the electric drive of the submersible centrifugal pump, in which a communication cable is placed to control the valves from the electric feed and control cable, which attaches the pump electric drive to the well electric feed and control station.
EFFECT: increasing operating efficiency of the well formations.
