线性胶压裂液是页岩气开采最关键的技术之一。以SRFP-1增稠剂、SRFC-1交联剂、SRCS-1黏土稳定剂和SRCU-1助排剂工业品为研究对象制备SRFP线性胶压裂液;评价了该压裂液体系的变剪切性能及对岩心基质伤害性能;将该压裂液在塔里木盆地某重点页岩气探井进行了现场应用。结果表明：SRFP线性胶压裂液在70~90℃条件下具有良好的抗剪切性能,对岩心基质伤害率小于20%,现场施工平均砂比为11.9%,返排液黏度小于5 m Pa·s。

英文摘要：

Linear gel fracturing fluid is one of the key technologies of shale gas exploitation. A SRFP linear gel fracturing fluid is synthesized by using SRFP-1 gelling, SRFC-1 cross-linker, SRCS-1 anti-swelling agent and SRCU-1 cleanup additive products as raw materials. The shearing resistance performance and the permeability damage rate of core matrix are studied. SRFP linear gel fracturing fluid is used in one important shale gas well which is located in Tarim Basin. The results Show that SRFP linear gel fracturing fluid has better shearing resistance performance at 70 - 90℃. The permeability damage rate of core matrix caused by SRFP linear gel fracturing fluid is less than 20%. The average sand ratio is 11.9% and the viscosity of flowback fluid is less than 5 mPa.s.
