METHOD OF SECONDARILY OPENING PRODUCTIVE FORMATION

摘要

FIELD: oil and gas production. SUBSTANCE: invention relates to opening productive formations in cased wells and aims at providing stable oil saturation of formation and stable collector characteristics when reopening formation, providing developing of well and putting it into operating condition, providing safe operation when opening formation at formation pressures above hydrostatic one. The aim is achieved by pumping in hydrocarbon liquid into the well followed by perforation, said liquid being high-molecular alcohols obtained as by-product in glycerol production. EFFECT: increased operation reliability. 1 dwgt
