中文摘要：针对油田开采中后期大量污水产生，油气成藏环境变差导致驱油率降低的现状，在实验室以表面张力法测定磺酸盐表面活性剂临界胶束浓度，根据CMC形成机理，考查了磺酸盐表面活性剂临界胶束形成前后，对应表面张力测定值的变化，通过油田污水对磺酸盐表面活性剂临界胶束浓度的影响实验及结果讨论，得到一些规律，为磺酸盐表面活性剂在复合驱技术中的更好应用提供理论依据。
英文摘要：In this paper, the critical micelle concentration of surfactant was measured by surface tension method. And the influence of oilfield sewage on the critical micelle concentration of sulfonate surfactant was studied. Besides, experiments were carried out to obtain some regularity, which provides a theoretical basis for the better application of sulfonate surfactant in compound flooding technology.
