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

FIELD: oil and gas production industry. SUBSTANCE: method allows for higher efficient action of displacing agents injected into reservoir such as water and gas due to prevention of outbursts of gas and water in vertical direction in zone adjacent to well. Maintaining at well head of water-gas injection well of water pressure value determined according to formula given in description ensures delivery of displacing agents in design quantities and in given intervals: water - into upper gas-saturated part, and gas - into lower oil-saturated part of reservoir. Regulation of water and gas injection process is effected with use of pressure gauges installed at head of water-gas injection well. EFFECT: high efficiency. 1 dwg
