摘要针对适合高温(90℃)高盐（TDS=95994mg/L)油藏的聚合物增强泡沫驱油体系（0.2%（w)PSDA十0.1%（w)TritonX-100十0.2%（w)KYPAM-II十地层水)开展其注入模式、气液比、剖面调整能力和现场试验评价。气和液同时注入就地发泡是最有效的注入模式，而气液交替注入效果最差，气液比明显影响驱油效率。在油藏条件下，优化气和液同时注入模式的气液体积比为3：1。双岩心驱替实验结果表明，泡沫驱明显提高高渗层和低渗层的采收率，具有良好的调剖改善能力，聚合物增强泡沫驱可提高原油平均采收率15.3%。现场试验结果表明，两口井组采用泡沫驱原油采收率效果显著。

Abstract:Aiming at the high temperature （90 C)and high salinity （TDS=95 994 mg/L) reservoirs , the injection mode, gas liquid ratio , profile control and field test of polymer enhanced foam flooding system (O.2 wt% PSDA+0.1wt% TritonX-100+0.2wt%KYPAM-II+formation water) were evaluated in this paper . The co-injection of gas and solution for foaming-in-site is the most effective mode , but the alternative injection of gas and solution is the worst . The gas liquid ratio may greatly affect the flooding efficiency . The optimized gas liquid ratio is proposed as 3 : 1 for co-injection mode at the reservoir condition . Results of dual cores flooding experiments indicate that the foam flooding can obviously increase oil recoveries of high and low permeability zones , the foam flooding has excellent profile control ability , polymer enhanced foam flooding can improve 15.3% average OOIP (original oil in place ) recovery . The field test results show that the effect of enhance oil recovery rate by using foam flooding is significant in two wells group .
Key words : high temperature, high salinity , foam flooding , polymer, injection mode, gas-liquid ratiocore displacement experiment
