摘　　要：通过开展减阻剂及配套添加剂优选,研发出一套高效减阻水体系,其配方为0.12%高效减阻剂JZ-1+0.2%防膨剂FP-1+0.1%助排剂ZP-1。该体系在高剪切速率下剪切稳定性好,黏度恢复率达94.7%;在高剪切速率下黏度较低,有利于压力传导,穿透层理,形成网缝,减阻率达76.7%,能够大幅降低施工摩阻;在低剪切速率下黏度较高,有利于支撑剂悬浮。同时该体系具有储层伤害小的特点,有利于储层保护,适用于页岩气深井压裂改造。A high auxiliary additives efficiency drag reduction water system was developed by choosing a drag reducer and its through optimization, and its formulation was identified as follows： 0.12% high efficiency drag reducer JZ - 1 ＋ 0.2% anti-swelling agent FP - 1 ＋ 0.1% cleanup additive ZP - 1. This system has good shear stability at high shear rate with the viscosity recovery rate of 94.7%. Its viscosity is low at high shear rate, which is beneficial to pressure transmission, stratification penetration and formation of net crack with the drag reduction rate being 76.7%. It can reduce construction friction drag substantially. Its viscosity is high at low shear rate, which is beneficial to the suspension of proppant. This system does low harm to reservoir, which is beneficial to the protection of reservoir and is suitable for deep shale gas well fracturing modification.
