摘　　要：综述了驱油用磺酸盐表面活性剂、羧酸盐表面活性剂、非离子-阴离子两性表面活性剂、烷基多糖苷表面活性剂、Gemini表面活性剂、甜菜碱表面活性剂的发展,指出Gemini表面活性剂、甜菜碱表面活性剂在油田中应用需解决的问题和国外近年较重视驱油用非离子-阴离子表面活性剂的趋势;总结了表面活性剂分子结构与降低界面张力性能的关系,指出研究甜菜碱类表面活性剂低界面张力形成机理对指导新型表面活性剂的合成有重要意义.The development of surfactants for oil displacement is summarized.These surfactants include sulfonate surfactant,carboxylate surfactant,nonionic-anionic amphoteric surfactant,alkyl polyglucoside surfactant,Gemini surfactant and betaine surfactant.The problems to be solved in the application of Gemini surfactant and betaine surfactant in oilfield are proposed and it is pointed out that nonionic-anionic amphoteric surfactant gains more attention at abroad in recent years.The relationship between the molecular structure of surfactants and the property of reducing interfacial tension is discussed,and it is held that the study on the low interfacial tension forming mechanism of betaine surfactant is of important guiding significance to the synthesis of novel surfactants.
