成果简介	NOVELTY - The device has a receiving pipe suspended from an electric centrifugal pump with a packer installed directly under a submersible motor of the electric centrifugal pump with a telemetry system for monitoring operation of a unit and having openings for an outlet of an extracted product above a packer, channels for the entry of oil and formation water located respectively in upper and lower parts of the receiving pipe, a unit for switching the flows of oil and water, and cylindrical chambers. Intermediate density floats are made of a cylindrical steel shell filled with ballast for regulating mass of the floats and placed in the cylindrical chambers installed in upper and lower parts of induction switches connected by an electric cable to a telemetry system of a submersible pump motor. Electromagnetic valves alternately close oil and water inlet channels in a flow switching unit at moments when induction switches are triggered. USE - Device for extracting formation fluids from an oil well with an electric submersible pump.
