FIELD: oil producing industry. SUBSTANCE: upper and lower parts of pool are developed by stages. Preliminarily withdrawn is oil through perforation intervals which open pool upper part. Withdrawal is carried out at reduced formation pressure down to fracture healing pressure but lower than pressure of oil saturation with gas. Gas is injected through injection wells to upper part. Then, lower part of perforation interval is isolated. EFFECT: prevented inrush of gas through fractures to zone of oil withdrawal in lower part of pool and higher oil recovery. 1 dwg
