Title: Method for development of oil deposit
Inventor: GORODILOV VIKTOR A
IPC: E21B43/20
Filed: 1996-07-05
Granted: 1997-11-20
Abstract: FIELD: oil production industry. SUBSTANCE: according to method, wells are arranged in rows in deposit. Oil is recovered through producing wells and working agent is injected through injection wells with subsequent formation of rows of injection wells which are perpendicular to main rows of injection wells by transferring number of producing wells to injection wells. Development is performed in cyclic mode. In each cycle before formation of rows of injection wells perpendicular to main rows, development is proceeded until reaching bed pressure which is 4-6% higher than initial pressure, then stopped are injection wells and rows of producing wells closest to rows of injection wells of main rows. Oil is recovered through producing wells in rows remote from rows of injection wells until bed pressure is reduced by 12-16% below initial value. After formation of rows of injection wells perpendicular to main rows of injection wells, started for operation are injection wells in perpendicular rows and stopped producing wells. Oil deposit is developed until bed pressure is increased by 4-6% above initial value. Stooped are injection wells of perpendicular rows and producing wells of rows closest to main rows of injection wells, and oil is recovered until bed pressure drops by 12-16% below initial value. This results in increased oil output. EFFECT: high efficiency.
