以胜利油田孤岛试验区原油为油相， 用正交试验筛选了碱／天然混合羧酸盐／聚合物驱油体系， 讨论了各组分对ＡＳＰ复合驱油体系油水瞬时界面张力的影响， 并探讨了各组分间的相互作用机理及其在油水界面的吸附机理．
Taking the crude oil in the experimental island of Shengli Oilfield as the oil phase, the orthogonal test was used to screen the alkali / natural mixed carboxylate / polymer flooding system. The influence of each component on the transient interfacial tension of ASP flooding system was discussed. The interaction mechanism of each component and its adsorption mechanism at oil-water interface were discussed.
