FIELD: oil and gas industry.
SUBSTANCE: system for removal of fluid medium from a certain zone of well shaft includes a single packer having external layer expanding in the well shaft across the expansion zone and containing many drain holes in expansion zone and many tubes connected to many drain holes, elastic inflatable balloon located inside external layer and pair of mechanical fastening devices located on opposite ends of external layer and having many turning flow elements connected to many tubes for adaptation to expansion of external layer with elastic inflatable balloon.
EFFECT: improved expansion degrees; higher depression pressure drops; enhanced support of formation in the zone, from which formation fluid media are taken.
