粘弹性表面活性剂压裂液与传统水基聚合物压裂液相比具有低伤害、低摩阻、易于彻底破胶等优点，在近年来成为压裂液领域的研究重点。介绍了粘弹性表面活性剂压裂液的粘弹性机理和破胶机理，并综述了粘弹性表面活性剂压裂液在国内外的研究应用现状。针对粘弹性表面活性剂压裂液目前存在的耐温性较差、成本偏高、在渗透率大于200-300mD的地层的滤失量偏大和在气藏不能自动破胶的问题，分析了问题产生的原因，并讨论了解决方案。

Visco-elastic surfactant fracturing fluid has become a focus of research due to the advantages such as low damage, low friction, ease of full gelout over traditional polymer frac- turing fluids. The mechanisms of visco-elastic surfactant fracturing fluid are introduced, the development and application status of visco-elastic surfactant fracturing fluid both abroad and at home are reviewed. Based on the problems such as poor temperature resistance, high cost, high leak-off in formations with permeabilities above about 200-300 mD and difficulty in breaking in gas reservoirs presented in the field applications, the cause of the problems are analyzed, and the solutions are given.
