根据静态吸附法研究了石油羧酸盐表面活性剂在岩心上的吸附损失，讨论了电解质浓度、离子强度及表面活性剂的一次抽提液与二次抽提液的复配对石油羧酸盐表面活性剂吸附量的影响，分析了碱／石油羧酸盐／聚合物（ＨＰＡＭ）三元复合体系中各组分的相互作用对羧酸根离子吸附的贡献。实验表明：表面活性剂的吸附量随着电解质的浓度及离子强度的增加而增大；在三元复合体系中石油羧酸盐的吸附量远远低于表面活性剂单独作用时的吸附量；三元复合驱油体系对于提高原油采收率具有广阔的应用前景。
According to the static adsorption method, the adsorption loss of petroleum carboxylate surfactant on the core was studied. The effects of electrolyte concentration, ionic strength and the combination of primary extractant and secondary extractant on the surface of petroleum carboxylate The influence of various components in the alkali / petroleum carboxylate / polymer (HPAM) ternary complex system on the adsorption of carboxylate ions was analyzed. The experimental results show that the adsorption amount of surfactant increases with the increase of electrolyte concentration and ionic strength; the adsorption amount of petroleum carboxylate in ternary system is much lower than that of surfactant alone; Yuan composite flooding system for improving oil recovery has broad application prospects.
