摘　　要：根据红岗油田萨尔图油层特征 ,筛选出了一种三元复合驱油体系 ,该体系与红岗油田萨尔图油层形成的界面张力可达到 10 -3 mN/m。该体系组成为 :0 .0 6 %表面活性剂S 96 + 1.5 %NaOH + 0 .2 %聚合物 + 0 .2 %助剂 ,在油层温度下与原油间界面张力 3× 10 -3 — 7× 10 -3 mN/m ,粘度 >2 0mPa·s ,在室内岩芯流动实验中 ,该三元复合驱油体系在水驱基础上提高采收率 10 %左右。An ASP flooding system is prepared for water flooded, high CO 2 containing reservoir strata Saertu of Hongyuan Oil Fields, Jilin, through a series of sieving experiments. It is composed of 0.06% commercial anionic surfactant S 96(of 25% concentration),1.5% NaOH,0.2% polymer HPAM, and 0.25 auxiliary. The minimum interfacial tension between the aqueous flooding solution in fresh water of salinity 400—500 ppm and the crude oil is of magnitude 10 -3 mN/m. In reservoir core experiments with the flooding solution(0.2PV), enhancement in oil recovery of some 10% is observed.
