摘　　要："Extended表面活性剂"是指在离子型表面活性剂中,特别是在阴离子型表面活性剂的疏水基与亲水离子头之间嵌入含聚氧丙烯链段的新型表面活性剂。结合文献报道和本课题组的前期研究成果,介绍了Extended表面活性剂的沿革与发展,着重从品种归属和合成反应两个方面进行总结,并预期了Extended表面活性剂在高温高盐油藏三次采油中良好的应用前景。指出进一步开发Extended表面活性剂的重点为:1)针对无碱驱油需要,合成抗高温高盐和耐水解的磺酸盐型Extended表面活性剂;2)开发磺基甜菜碱型Extended表面活性剂,预期将有更好的性能和用武之地;3)研究Extended表面活性剂与其他表面活性剂的复配,拓展其在三次采油及其他领域中的应用。Extended surfactants are a novel type of surfactants, especially anionic surfactants, of which a polyoxypropylene chain is embedded between hydrophilic ionic head and hydrophobic group tail to meet the needs of tertiary oil recovery. This article, combined literature reports with our previous research, describes evolution and development of the Extended surfactants, and summarizes the Extended surfactants in the disciplines of type and synthesis. And the potential application of the Extended surfactants in tertiary oil recovery in high temperature and high salinity oilfield is highly prospected too. It is noted that further development of the Extended surfactant should focus on the following aspects： 1） to synthesize the nonhydrolyzable sulfonated Extended surfactants that are tolerant to high temperature and high salinity and thus fitting the need of non-alkali oil recovery; 2） to synthesize the sulfobetaine-type Extended surfactants that are expected to have better performance and application; 3） to synergize the Extended surfactants with other surfactants to expand the application in tertiary oil recovery and other fields.
