摘　　要：针对聚合物驱后地层非均质状况进一步恶化、剩余油分布更加复杂分散、至今仍没有较好的接替技术等问题,提出了复合热载体泡沫驱提高采收率技术。通过单管模型、双管模型驱油效率实验,分析了复合热载体泡沫驱提高采收率的主要机理,认为复合热载体泡沫驱具有化学驱、氮气驱、二氧化碳驱、蒸汽热力驱和泡沫驱等多重优点,在聚合物驱后仍能大幅度提高采收率,实验岩心采收率提高幅度可达13.59%,因此,该技术可以作为聚合物驱后提高采收率的一种有效接替技术。After polymer flooding,heterogeneity of the formations got more serious,and the distribution of remaining oil became more complex and more dispersive,and there is no better sequent technology. Combined thermal carrier foam flooding was proposed for enhancing recovery efficiency. Based on the oil displacement by single and double column run,the main displacement mechanism was researched. The results show that combined thermal carrier foam flooding has advantages of chemical flooding,nitrogen flooding,carbon dioxide flooding,steam thermal flooding and foam flooding,thus it can improve oil recovery greatly after polymer flooding. Oil recovery may be enhanced 13.59% after the experiments. So it is an effective replaced technology after polymer flooding.
