ASSEMBLY AND METHOD FOR PROLONGATION OF EXPLOITATION LIFE OF OIL FIELDS Russian patent published in 1997 - IPC

FIELD: oil and gas production. SUBSTANCE: assembly of invention includes productive wells and corresponding equipment. On a platform, compressors are installed to force compressed air through pipes into wells extending towards fired oil formation. Method consists in pumping in water and air into oil bed, between two wells in oil bed a common cavity being preliminarily created using explosion. One of the wells is expanded and platform with equipment is installed over the well to fire oil-bearing bed and supply air and water to form steam-gas mixture in above-mentioned cavity. Steam-gas mixture is used to actuate compressors, pump, and hydraulic turbine with electricity-generator. EFFECT: prolonged well lifetime. 8 cl, 6 dwg
