METHOD FOR DEVELOPMENT OF OIL DEPOSIT Russian patent published in 2000 - IPC

Abstract RU 2144614 C1

FIELD: oil production industry. SUBSTANCE: method relates to development of oil deposits which are close to non-uniform reservoirs. According to method, injected through injection wells are working agent and water solution of surface-active substance. Oil is recovered through producing wells. Water solution of surface-active substance, prior to injection is foamed until reaching saturation pressure (Ps.) of produced solution by air at given gas factor and at bed temperature which is determined from following relation: Ps. = (0.1 - 0.9) Pb. where Pb.- bed pressure, MPa. Application of method enhances efficiency of operation. EFFECT: higher efficiency. 1 cl
