摘　　要：聚合物和表面活性剂之间存在着协同效应,这种效应有利于改善聚/表二元复合驱油体系的驱油效果。研究了线型性聚合物LFP323与阴离子表面活性剂SDBS体系的配方,及其界面特性、注入性以及在低渗透条件下的驱油性能。结果表明,该二元体系表现出好的界面张力和良好的注入性,在低渗透岩心中获得了较好的驱油效果。There was a synergistic effect between the water - soluble polymers and surfactants, which can improve the sweeping efficiency of polymer/surfactant system. The interfacial characteristics, injecting property and oil sweeping efficiency in low - permeability cores of LFP323 and SDBS system were studied and the results indicated that the dual - compound system had excellent interracial tension and injection and the flooding effects was in low -permeability cores.
