双子表面活性剂的研究进展

Study advances of Gemini surfactants

复合驱是一种继聚合物驱之后的三次采油新方法,它可以充分发挥各化学剂的增效协同作用,大幅度提高驱油效率。从复合驱油对表面活性剂的要求出发,分析了传统表面活性剂面临的挑战,对具有发展前景的双子表面活性剂的结构与性能及国内外的研究状况进行了评述。指出新型复合驱油技术的关键是研制抗盐性能强的双子表面活性剂。

Combination flooding is a new method of tertiary oil recovery after polymer flooding. It can give full play to synergism of each chemical agent in raising oil displacement efficiency greatly. Based on the requirements of combination flooding on surfactants, challenges that traditional surfactants must face were analyzed. The structure, performance and research situation at home and abroad of the Gemini surfactant were commented, which has good prospects. It was pointed out that development and study of anti-salty Gemini surfactant were the key of new combination flooding technology.
