摘要：针对蒸汽吞吐过程中由于能量不足以及严重汽审等导致热效率低、吞吐效果变差的问题，从室内物理模拟以及数值模拟两方面，开展了在蒸汽中添加气体及高温泡沫以改善蒸汽吞唑开发效果的研究。首先，通过引入泡沫综合指数，筛选了合适的发泡剂；其次，进行了4组宝内平行双管实验，分别为单纯蒸汽驱、蒸汽-烟道气泡沫驱、蒸汽一氮气泡沫驱以及蒸汽-氮气驱。实验结果表明：在注入条件相同的情况下，蒸汽-烟道气泡沫驱和蒸汽-氮气泡沫驱均能够有效地对墙高渗管，启动低渗管，与单纯蒸汽驱相比，采出程度最高分别提高了28.98%和26.04%；蒸汽-氮气驱调剖效果有限，不能有效地启动低渗管，采出程度比单纯蒸汽驱提高了10.56%。结合物理模数的结累，采用数值模拟方法，分析了地层参数对烟道气一泡沫辅助吞吐和单纯蒸汽吞吐开发效果的影响，结果显示，对于层薄、油稠的非均质油藏，烟道气一泡沫辅助吞吐与单纯燕汽吞吐相比具有是著的优势，能够有效地提高蒸汽吞吐开发效果。对河南油田井楼零区烟道气一泡沫辅助蒸汽吞吐方案进行了参数优化，得到最佳目注汽量为100m，最佳气汽比为12，最佳树井时间为7d。

Abstraet: With consideration of low thermal conducting efficiency induced by insufficiency in energy and severe steam channel-ing during steam stimulation, researches have been conducted through indoor physical simulation and numerical simulation by adding gas and high-temperature foam to enhance performances of steam stimulation. First of all, comprehensive foam indicators have been introduced to identify the optimal foaming agent. Secondly, four indoor parallel dual-pipe tests, namely pure steam flooding, steam-flue gas foam flooding, steam-nitrogen foam flooding and steam-nitrogen flooding, were performed. Test results show under identical flood se ieaado [eas aaaaa e poo eo area e oo eo e aneas o so to mobilize low-permeability channels. Compared with pure steam flooding, the new technique can enhance oil recovery by 28.98% and 26.04%, respectively. The steam-nitrogen flooding displayed limited profile-control performances because it failed to mobilize low-permeability channels effectively. It has improved oil recovery by 10.56% higher than that of pure steam flooding. With consideration of
