摘要: 根据室内模型实验结果,泡沫复合驱可比水驱提高采收率30%。在同一层位萨Ⅲ3-7层水气交替试验(WAG)后,北二东泡沫复合驱试验区于1997年2月开始泡沫复合体系的注入。随着气液交替周期的增加,气窜现象得到有效的控制,油层中形成了泡沫。目前已见到良好效果,含水大幅度下降,油层中明显地形成了含油富集区。北二东泡沫复合驱全区阶段采出程度为10.64%,中心井区阶段采出程度为10.34%。中心井区总采出程度达到4.96%。目前试验仍处于实施过程中,最终采收率将依据物模、数模及矿场开采规律综合进行评价。

Abstract: Based on the results of laboratory, the incremental oil recovery of ASP (Alkaline-Surfactant-Polymer)-Foam flooding is 30% higher than that of the waterflooding. After the WAG injection in the same layer SⅢ3-7,the ASP-Foam flooding was conducted on Feb.24,1997.With the injection of ASP-Foam system, gas channeling has been controlled effectively,and foam was formed in the reservoir. Favorable effect has been achieved,the water cut decreased greatly in the two central wells,and obvious the oil bank has formed. Presently,the stage oil recovery is 10.64% in the whole pilot area,and is 10.34% in the central area.The total oil recovery is 54.96% in the central area. The ultimate oil recovery will be evaluated by core flooding,numerical simulation and performance of pilot test.
