Beschreibung
Zusammenfassung:	FIELD: oil producing industry. ^ SUBSTANCE: invention can be used at production of oil with associated petroleum gas. Proposed system contains submersible electric motor with hydraulic protection, submersible pump and gas separator containing the following members arranged in tandem in housing in direction of flow running: screw, axial hole-enlargement wheel, separation drum with ribs, separated gas removal unit directing gas into annulus space and separated liquid to submersible pump intake. Angle beta of trailing edge of hole-enlargement wheel is from 135o to 145o. In one of design of system with range of 135
