Granted: 2008-06-27
Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to the oil and gas industry, particularly to the methods for developing the oil deposits with gas cap at early stage. The method reduces the danger of gas outbreak from the gas cap to the producing wells at the early stage of developing the deposit with gas cap, and expenditures. The method includes directional drilling of producing, developing and gas wells, injecting water into the oil bed via the injection wells, oil selection via producing wells and injecting the displacing agent into the gas cap. According to the invention, at the early stage of development of the oil deposit, the bed pressure in the gas cap is maintained at the level higher than initial value, without waiting for its decrease. The water-gas mixture containing 80 to 95 mass percent of gas, is used as a displacing agent. At that, water is preliminary purified and heated to the temperature higher than 30°C, which prevents hydrates formation, and is tolerant for the device supplying the water-gas mixture into the gas cap. As a device, the booster pump-and-compressor station is used. 
     EFFECT: danger of gas outbreak from the gas cap to the producing wells at the early stage of developing the deposit with gas cap, and expenditures are reduced.
