Shear recovery for viscosifying surfactants in stimulation fluids

A method of reducing shear recovery time of a viscosifying surfactant fluid system that includes introducing a viscosifying surfactant fluid system into a subterranean formation, wherein the fluid includes a major portion of a surfactant and a hydrophobically-modified associative polymer in a concentration sufficient to shorten the shear recovery time of the fluid system compared to the shear recovery time of the fluid system without the polymer. 种减少增稠表面活性剂流体体系的剪切恢复时间的方法，该方法包括将增稠表面活性剂流体体系引入地下地层中，其中该流体包含主要部分的表面活性剂和疏水改性的缔合聚合物，与不含该聚合物的流体系统的剪切恢复时间相比，该缔合聚合物处于足以缩短该流体系统的剪切恢复时间的浓度。
