FIELD: oil and gas industry.
SUBSTANCE: unit contains motor driven centrifugal pump, unit for flow regulating and formation products metering, bottomhole and bearing packers with anchor devices, and connecting assembly connecting the unit for flow regulating and formation products metering with the supporting packer. The motor driven centrifugal pump has remote mechanical system unit, and is connected by the power cable with the control station. The unit for flow regulating and formation products metering contains the regulated motor driven valves installed in separate channels connected via the windows with borehole. The motor driven valves are connected by cable via the cable connector with the ground control panel. The connecting assembly contains pipe elements of the movable connection of the end unions with the flared end, and smooth unions with guide cone and cuff for the tight telescopic connection with end unions, creating the coaxial through channels and ensuring unit-by-unit installation and dismounting of the pump unit. The unions are connected with bore of the support packer by the straight multi-channel coupling, to the later the branch of the well product taking from the bottom formation is connected, it is free located in the central hole of the radial-through coupling equipped with the ring cuff, and connected to the bore of the support packer, creating with it a coaxial channel connected with the top formation via the radial channels of the radial-through coupling, that is interfaced with the tail connected with the bore of the bottom hole packer. On the internal surface of the external end union a ring groove is made to hook the support and bottom hole packers by the installation tool during the unit-by-unit installation and dismounting of the pump unit. The unit for flow regulating and formation products metering is connected with pump by means of the coupling, in its wall a window is made for the well product contact with the remote mechanical system unit. In the separate channels the Instrument sensors of the product parameters are installed, they are connected by cable located in the cavity of the connecting coupling and passing through the window in its wall, and borehole space connected with the control panel. The motor driven valve and Instrument sensors can be connected by cable from the cable connector with the remote mechanical system unit, the latter is connected via the power cable with the control system and control panel.
EFFECT: increased efficiency of the wells operation.
