FIELD: oil and gas industry.
SUBSTANCE: according to the first version the installation comprises flow column, two packers, ground control station, electric cable feeding electric motor of a submersible pump, borehole chamber, which body is limited at butt ends by crossover couplings communicated through longitudinal channels of the couplings to outlet fitting of the submersible pump at the one side and to the flow column at the other side, two units regulating influx and recording fluid for the lower and upper seams separately, which contain telemetric modules measuring physical values of fluids state and adjustable electric valves. The lower packer is set above the lower seam outside the shank. The upper packer is installed below the upper seam; it forms with the lower packer an interpacker section of the well, in which cavity there is the submersible pump with input module and electric motor, the latter is connected to the shank connecting the lower seam to the interpacker section through channels of the shank and adjustable electric valve of the unit regulating influx and recording fluid, which is placed in the shank covering the cavity and connected by communications cable to the ground control station. In the borehole chamber there is a cylinder placed concentrically to the body and matched to crossover couplings communicating the upper seam to the interpacker section through radial channels of couplings and adjustable electric valve of the unit regulating influx and recording fluid, which is placed in the upper coupling and connected by communications cable to the ground control station.
EFFECT: increased efficiency of wells operation.
