摘要
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．
The effect of each component of two alkali/surfactant/polymer flooding systems which use a low price natural mixed carboxylate as the major surfactant on transient and minimum interfacial tension is discussed in this paper. It is found that each component of the ASP flooding systems has an optimum concentration making the minimum interfacial tension on O/W interface lowest: alkali 1.0%, surfactant 0.5%, polymer 0.1%. We also probe into the mechanism of interaction in each component and their adsorption on O/W interface initially.
