FIELD: oil-and-gas industry.
SUBSTANCE: packers are arranged between well beds to form well packed spaces. Well spaces are communicated by common tube with its top end connected to well extraction pump or transport system at well mouth. Said common tube bottom end is arranged at well lower thick bed and has cuts at the level of every well space. Jet pups are installed in common tube cuts. Well spaces in the zone of thin beds and above all beds are communicated by pipes arranged tightly to pass through well spaces in zones of thick beds.
EFFECT: elimination of bed cross flows, replacement of cross flows by extraction of fluid from thinner beds, removal of bypass gases.
