摘要(Abstract)：

采用填砂模型驱替、吞吐实验及油藏数值模拟,研究蒸汽(热水)—空气驱替和空气辅助蒸汽吞吐规律,分析空气辅助蒸汽吞吐的采油机理.结果表明:100℃温度时,注入空气使热水驱的驱油效率降低,热水—空气驱采出稠油的黏度较热水驱采出稠油的升高20.43%;200℃温度时,蒸汽—空气驱与蒸汽驱的开采效果差别不明显,蒸汽—空气驱采出稠油的黏度较蒸汽驱采出稠油的升高10.80%.蒸汽(热水)—空气驱采出稠油的沥青质质量分数高于蒸汽(或热水)驱采出稠油的.蒸汽—空气驱采出气的O2体积分数低于3%,CO2体积分数为3%~5%.在蒸汽吞吐过程中,注入空气与稠油反应而被消耗,利用未反应的N2及生成的CO2等烟气的增压助排、气体降黏、生热、提高热效率和固砂等作用,能够改善蒸汽吞吐开采的效果,与N2辅助蒸汽吞吐增产效果相当,较蒸汽吞吐周期采油量提高20%~30%,吞吐开采轮次越高,增产效果越明显.
