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

FIELD: oil production industry. SUBSTANCE: this can be used in development of oil deposits with large number of stopped wells. According to method, working agent is injected through injection wells, and oil is recovered through producing wells, and some wells are stopped. Selected in deposit is development section with producing and injection wells having hydrodynamic connection between each other. Separated in this section is zone of higher oil saturation, filtration flow is formed through zone of higher oil saturation by putting into operation earlier stopped producing wells located beyond zone of higher oil saturation over its perimeter and within its limits. In addition, introduced in operation are earlier stopped injection wells located behind zone of higher oil saturation. Initially, injection wells are put into operation, then earlier stopped producing wells are started to operate. EFFECT: high efficiency. 2 cl, 1 dwg, 4 tbl
