摘　　要：黏弹性表面活性剂基压裂液在回排过程中容易出现破胶不完全的情况,甚至还会存在大量残渣,对贮层产生较大的影响。因此,为了改善新式压裂液的破胶问题,早在20世纪90年代末,就研发出了这种表面活性剂的新式压裂液。这种压裂液没有交联、破胶的过程,其流体参数本身的结构黏度就可以完成对支撑物的高效运输。因为没有交联、破胶,其返排效果也非常好,对地层储层结构的影响也较小。因此,就当前黏弹性表面活性剂基压裂液的研究情况进行分析。Viscoelastic surfactant fracturing fluid based fracturing fluid is prone to incomplete gel breaking during the flowback process,and there will even be a large number of residues in the broken paste,which will have a great impact on the reservoir.Therefore,in order to improve the gel breaking problem of the new fracturing fluid,as early as the late 1990s,people developed a new fracturing fluid with this surfactant.This fracturing fluid has no crosslinking and gel breaking process,and its structural viscosity of fluid parameters can complete efficient transportation of supports.Because there is no cross-linking and gel breaking,the flowback effect is also very good,and the impact on the formation and reservoir structure is also small.Therefore,this paper analyzes the current research situation of viscoelastic surfactant overstock fracturing fluid.
