METHOD OF OIL POOL DEVELOPMENT Russian patent published in 2000 - IPC

FIELD: oil producing industry; applicable in development of oil pool with low-permeable reservoir. SUBSTANCE: method includes oil withdrawal through producing wells and injection of working agent through injection wells, and performance of stimulation operations. In latter case, placed to bottom of injection well is alkali, alkali-earth or alloy on its base in isolated from well fluid state. Contacting of alkali, alkali-earth or alloy on its base is organized with fluid. Reaction products are pumped into bottom-hole zone and process holding is effected. Mud acid is injected. Reaction products are forced into formation by working agent. Process holding is effected before forcing of reaction products into formation. Formation fluid is withdrawn from bottom-hole zone in volume less than volume of injected mud acid, and well is washed. Prior to performance of stimulation operations, well bottom is filled with acid solution. EFFECT: higher oil recovery of pool. 3 cl, 3 ex
