FIELD: oil and gas industry.
SUBSTANCE: single-packer device for dual fluid production from two well reservoirs contains a centrifugal pump with a receipt module and electric drive equipped with housing and run in into the casing pipe at the flow string, a control valve which includes a sleeve for criss-cross flow of fluids connected to the casing and thus forming a chamber for mixing fluids from different well reservoirs that is communicated to eccentric channels of the sleeve from one side and to the pump receipt module at the other side and by the central channel to the upper well reservoir through radial channels of the sleeve. In the central channel of the sleeve there is a fluid flow cutter with an electric drive and an option of control from the surface location through an electric cable, and a packer. The device is equipped additionally by a control valve placed in cavity of the liner connected to the sleeve for criss-cross flow of fluids, from below the liner is coupled to a docking unit where additional control valve is installed. The docking unit is connected to the device taking fluid from the lower well reservoir equipped with the above packer. The control valves are equipped with sensor packages of control and measuring instruments and coupled to the unit of telemetry control system, the latter is installed at butt end of the pump electric derive with an option of control for the control valves from the surface location through an electric cable or automatic control from sensors measuring physical parameters of the fluids.
EFFECT: increased efficiency of well operation.
