摘　　要：针对阳离子型表面活性剂易在砂岩上产生吸附作用而导致储层伤害问题,对一种阴离子型表面活性剂清洁压裂液配方进行了优化,并对该压裂液性能进行了评价。研究表明,该压裂液具有较好的耐温耐剪切性能和破胶性能,与储层配伍性好,对储层伤害小。同时,现场试验也取得了较好的增油效果,说明了该压裂液具有改善油田压裂施工效果的作用。Based on reservoir damage caused by cationic surfactant adsorbed on sandstone,a formula of kind of anionic surfactant clean fracturing fluid is optimized in this paper,and the performance of the clean fracturing fluid is evaluated.Research shows that the fracturing fluid has good temperature-tolerate and shear-tolerate properties,excellent gel breaking performance,good compatibility with reservoir,and it has low formation damage.At the same time,in the field test it has achieves good effect of oil increase,it illustrates that the fracturing fluid has the effect for improving its performance.
