METHOD FOR DEVELOPMENT OF OIL AND GAS DEPOSIT Russian patent published in 1997 - IPC

FIELD: oil and as industry. SUBSTANCE: method implies drilling of wells and opening of oil saturated intervals with subsequent withdrawal of liquid from production wells in conditions of pool flooding through injection wells. Withdrawal of liquid from production wells is effected at modes of current critical outputs of liquid without gas. Injection of working agent into injection wells is performed at flow rate not exceeding total rate of fluid withdrawal from production wells. Realization of method increases current critical output of oil without gas for longer period of profitable development of oil and gas deposit with increased final coefficient of oil withdrawal. EFFECT: high efficiency. 5 cl, 7 dwg, 2 tbl
