METHOD OF OIL POOL DEVELOPMENT Russian patent published in 2002 - IPC

FIELD: oil-producing industry. SUBSTANCE: method includes injection of working agent through injection wells, oil withdrawal through producing wells, repairs of wells and their engagement. In so doing, subject to determination is time needed for front of pressure change reaching producing well from injection one during disturbing actions characteristic for engagement of injection well; time of reduction of formation pressure down to permissible level in operation of producing well. After repair, injection well is engaged. Minimal time of engagement of producing well is determined by difference between time needed for front of pressure change reaching the producing well from injection one and time of reduction of formation pressure down to permissible level in operation of producing well. Proposed method is used in development of multilayer pools. EFFECT: higher rate of oil pool development. 1 ex
