摘要/Abstract

摘要： 以黏弹性表面活性剂(VES)组成结构为基础,详细阐述了胶束的转变机制;通过对黏弹性表面活性剂在国内外油田应用现状的广泛调研,系统介绍了不同类型的VES在清洁压裂液、自转向酸等工艺技术中的作用机理及应用情况,并对实际应用时存在的问题进行了总结分析。VES具有特殊的分子组成和流变性质,在压裂、酸化、三次采油、钻井液以及流体减阻输送等方面有着广阔的应用前景。最后对黏弹性表面活性剂工作重点和研究方向进行了展望。

Abstract: Based on the composition structure of viscoelastic surfactant (VES),micelle change mechanism of VES was described.Through wide investigations on present situation of VES in Chinese and foreign oilfields,mechanisms and applications of separate types of VES in clear fracturing fluid,self-diverting acid and some other techniques were systematically introduced.Moreover,existing problems were summarized and studied.VES has wide application prospects in fracturing,acidizing,tertiary oil recovery,drilling fluid and fluids drag-reducing transportation because of its special micellar structure and rheological property.At the end,working emphases and research trends in this field were proposed.

Key words: viscoelastic surfactant, clean fracturing fluid, self-diverting acid, application
