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。

关键词: 碱/表面活性剂/聚合物复合驱油体系, 瞬时界面张力, 天然混合羧酸盐

Abstract: 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 ASPflooding 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.

Key words: ASP-flooding systems, Transient interfacial tension, Natural mixed carboxylate
