摘要： 在典型蒸汽吞吐井建模基础上，对不同注入方式下烟道气辅助超稠油蒸汽吞吐的开发效果进行数值模拟，结果表明，烟道气辅助超稠油蒸汽吞吐可以提高能量利用效率，减少蒸汽注入量，提高累计油汽比，还可减少环境污染。优化后的注入参数为：烟道气周期注入量60 000 m3，烟道气注入速度800 m3/h，蒸汽周期注入量1 000 t，焖井时间为3~5 d，周期时间6个月，烟道气中CO2含量大于20%，注入温度大于100℃时，更有利于提高原油产量。

Abstract: Based on the foundation of typical steam huff and puff well model, the performance of flue gas assisted steam huff and puff for super?heavy oil reservoir was studied by numerical stimulation. The results show that flue gas assisted steam huff and puff for super?heavy oilcan improve energy utilization efficiency, reduce the volume of steam injection and improve cumulative oil steam ratio, meanwhile, reduce the environment pollution. The optimized injection parameters are then obtained, such as that the cyclic injection volume of flue gas is 60 000 m3, the injection rate of flue gas is 800 m3/h, the cyclic injection volume of steam is 1 000 t, the soak time is not less than 3 d, the cyclic time is 6 mon, besides, the CO2 content in flue gas is more than 20% and the flue gas injection temperature is higher than 100℃ are also beneficial to improve the oil production
