Title: The study of foam flooding in high water cut stage using computer numerical simulation
Abstract: This paper presents the method of computer numerical simulation of foam flooding in reservoir high water cut period. According to feature of foam flooding, foam impacting on the gas mobility is taken into consideration, the mathematical model of foam flooding has been established and a numerical simulation software has been developed. Taking the La8-182 well block of Lamadian oilfield for example, injection mode and injection parameters are optimized. The development effects have been predicted and the residual oil distribution has been given. Taken the geologic characters of pilot site and economic aspect into consideration, foam and water alternating injection has been chosen, and the injection parameters are that daily gas injection rate is 3000m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> /d, foam agent concentration is 1000mg/L and alternating injection semiperiod is 20d. According to the results of prediction, by the end of 2018, the degree of reserve recovery of foam flooding is 23.59% and enhances recovery 15.01% contrasting to water flooding.
