摘　　要：泡沫剂辅助蒸汽驱过程实验优化参数为:气液比1∶1,浓度0.5%,注入时机为低含水率。利用优化的参数开展了泡沫剂/驱油剂辅助蒸汽驱单双管实验,结果表明:1蒸汽驱后,注入驱油剂或泡沫剂,采收率分别提高25.7%和28.4%,两者可以大幅度提高采收率;2单管蒸汽驱阶段的平均采收率为60.25%,而非均质双管蒸汽驱阶段采收率为33.6%,表明非均质性增加,蒸汽驱采收率下降;3驱油剂/泡沫剂辅助蒸汽驱提高采收率58.9%,大于单独泡沫剂或驱油剂辅助蒸汽驱效果,表明化学剂协同作用可以更好的提高采收率;4实验结束后,填砂管中局部油砂的含油饱和度为零,表明驱油剂或泡沫剂辅助蒸汽驱实验具有很高的洗油效率。Foam auxiliarg steam flooding process parameters are that gas liquid ratio is 1∶ 1,concentration is 0. 5%,and injection time is low water cut. The injection of homemade alkylbenzene sulfonate surfactant and foam agent are conducted in single tube and double tubes displacement experiment devices. The results show that 1 injection of alkylbenzene sulfonate surfactant or foam agent can enhance recovery25. 7% and 28. 4% respectively; 2 recovery of single tube experiment during steam flooding stage is60. 25%,which is higher than that of double tubes. Heterogeneity double pipe steam flooding phase recovery is 33. 6%. The results show that heterogeneity reduce the recovery; 3 synergy injection of alkylbenzene sulfonate surfactant and foam agent can enhance recovery 58. 9%,which is higher than that of single injection; 4oil saturation of part of sands is zero in the end of experiment. That results show that alkylbenzene sulfonate surfactant and foam agent have high displacement efficiency.
