METHOD FOR DEVELOPMENT OF LINEAR OIL BED

FIELD: oil production industry. SUBSTANCE: in development of linear oil deposit, oil is recovered through producing wells until bed pressure is reduced by 12-14% of its initial value. Oil deposit is restricted by lines of external contour of oil-bearing zone and by boundary lines of displacement for...

Zusammenfassung:	FIELD: oil production industry. SUBSTANCE: in development of linear oil deposit, oil is recovered through producing wells until bed pressure is reduced by 12-14% of its initial value. Oil deposit is restricted by lines of external contour of oil-bearing zone and by boundary lines of displacement for non-reservoir. Injection wells are located along lines of external contour of oil-bearing zone and along boundary lines at points where thickness of oil-saturated portion of productive bed is less than 2 m. Further development of oil deposit is carried out in conditions of bed pressure increase annually by 3-5% until reaching initial bed pressure. Application of aforesaid method allows for increasing oil recovery from deposit. EFFECT: higher efficiency.
