METHOD FOR PRODUCTION OF OIL OR GAS Russian patent published in 1996 - IPC

FIELD: oil and gas producing industry; applicable in production of hydrocarbon fuel with less economical damage to nature in development of oil fields. SUBSTANCE: method for production of oil or gas includes drilling of blasting wells down to the middle of water impervious layer found directly over bill (gas) bearing porous layer. Blasting wells are located between development wells of all oil (gas) field. Wells are sunk by means of percussive drilling with excitation of resonance vibrations in water impervious layer down to which they are drilled. Placed into wells are, first, small charges and then multi-ton charges. They are simultaneously blasted in two stages in all blasting wells of one oil (gas) field. After explosions, in some period of time, during which oil (gas) is recovered from producing wells, supplied to blasting wells is fuel mixture of natural gas and air with subsequent ignition of fuel mixture. During the last stage of development of the oil (gas) field, water in injected at high pressure to sustain the formation pressure in the oil formation high enough to produce oil (gas). With the favorable geological conditions, nuclear charges of the tactical nuclear weapon, subject to disposal, may be used in the blasting wells. EFFECT: higher efficiency. 3 cl, 5 dwg
