摘　　要：双子表面活性剂因其高界面活性、低临界胶束浓度、低浓度时增粘效果明显,在清洁压裂液增稠方面潜力巨大。而溶液胶束结构的形态及变化与溶液粘度密切相关,因此准确表征不同浓度下双子表面活性剂溶液胶束微观结构形态及变化特征具有重要理论指导意义。在大量调研表面活性剂溶液胶束结构形态检测方法与表征的基础上,重点阐述了可用于双子表面活性剂溶液胶束微观结构表征的研究方法及其研究发展现状。Due to its low critical micelle concentration,high interfacial activity and good thickening effect in low concentration,gemini surfactant has great potential in the thickening of the clean fracturing fluid.The solution viscosity is closely related to the change of the micellar shape,so it has important theoretical significance to accurately characterize the micellar shape and the change of the micellar shape in different concentrations.In this paper,a large number of methods on characterizing the micellar shape of surfactant were investigated,the research methods to characterize the micellar shape of gemini surfactants in different concentration were discussed.
