METHOD FOR DEVELOPMENT OF OIL DEPOSITS Russian patent published in 1999 - IPC

FIELD: oil production industry. SUBSTANCE: according to method, wells are drilled and oil-saturated intervals are opened with subsequent recovery of liquid from producing wells and injection of air into bed through injection wells. Intensity of air injection into bed is preset proceeding from ensuring maximal possible binding of oxygen with residual oil in process of its oxidizing until reaching value of content of oxygen in gaseous phase at bottom hole of producing wells not over 10% volume. Application of aforesaid method increases oil recovery factor and improves explosion safety. EFFECT: higher efficiency. 7 cl
