摘　　要：利用一种Gemini季铵盐表面活性剂WHX与有机盐复配出VES压裂液体系并进行了室内性能评价。结果表明,该压裂液体系具有粘弹性,破胶性能好,配制简单方便,3%WHX+3%有机酸盐压裂液体系可在70℃下使用。压裂液为假塑性流体类型,其稠度指数K'=4.059m Pa·s^(0.3748),流体行为指数n'=0.3748。VES fracturing fluid system was prepared from a Gemini quaternary ammonium surfactant WHX with organic salt compound to make indoor performance evaluation. The result shows that this fracturing fluid system has viscoelasticity. The gel breaking performance is good. Besides, it＇s easy to be prepared. 3%WHX＋ 3% organic acid salt fracturing system can be used below 70℃. The fracturing fluid is pseudoplastie fluid. The consistency index is K＇=4.059mPa·s0.3748, and fluid behavior index is n＇=0.3748.
