Zusammenfassung:	FIELD: oil production industry, particularly methods or devices for cementing, for plugging holes, crevices, or the like. ^ SUBSTANCE: device comprises inflatable packers to be lowered into well along with flow string. One flow string end is closed to provide simultaneous well bore packing, another end is connected to production equipment. Flow string is provided with centralizers located near inflatable packers. Formed in flow string are additional holes located opposite to packers. Well pump is installed inside flow string. High-pressure water conduit having low diameter is connected to above holes. Flow string has perforated orifices created between inflatable packers. ^ EFFECT: extended operational capabilities. ^ 1 dwg
