METHOD OF DEVELOPING NONUNIFORM OIL POOL AT LATE STAGE

摘要

FIELD: oil-producing industry. SUBSTANCE: in development of oil pool at late stage, products are withdrawn through producing wells. Working agent is injected through injection wells and additional wells are drilled on areas with maximum hydrodynamic communication between wells. Closed flooding system is formed. Fluid production rate of producing wells is to be equal to accumulated injectivity of injection wells acting on producing well. Production rate of producing well is increased due to additional perforation, hydraulic fracture and making side bores. EFFECT: higher oil recovery for pool. 1 ex
