摘要
By using the CMG-STARS simulator, the migration laws of flue gas in the steam chamber at flue gas-steam assisted gravity drainage technology were researched. The speed of the steam chamber expanding and the variation of the shape of the steam chamber were studied after flue gas injected. The change rules of oil saturation, viscosity, pressure and temperature were analyzed. The injection parameters of flue gas were optimized by reservoir numerical simulation. With the optimized injection parameters, the development effects of flue gas-steam assisted gravity drainage technology and conventional SAGD were compared. The results show that the optimized steam injection temperature is 280 °C, the injection rate is 150 m3/d, and the flue gas and steam ratio is 1.0. With the optimized injection parameters, the cumulative oil production increases by 2.0 kt, and oil recovery efficiency increases by 7% using the flue gas-steam assisted gravity drainage technology compared with conventional SAGD. The development effect of flue gas-steam assisted gravity drainage technology is better.
