METHOD FOR DEVELOPMENT OF OIL DEPOSITS Russian patent published in 1998 - IPC

FIELD: oil production industry. SUBSTANCE: according to method, at initial stage of developing oil deposit drilled are both producing and injection wells. As injection wells are being readied working agent is injected into them so that bottom-hole pressure of injection wells is not higher than pressure of hydraulic fracturing of oil bed. With that, producing wells are preserved with no product recovery from them. Injection of working agent is continued until pressure in bed reaches determined value P. Value P is determined basing on collecting properties of bed and viscosity of bed oil with knowing total daily production rate through oil deposit. EFFECT: higher efficiency. 1 cl, 1 dwg
