摘　　要：优选了VES压裂液体系,最优配比为黏弹性表面活性剂VES 4%,助剂1.0%,还研究了体系的耐温、抗剪切、抗盐、破胶性能。结果显示,随着温度的升高,VES压裂液的黏度有明显的变化。不同的无机盐对VES压裂液有完全不同的影响,NH4C l具有明显的增黏作用,而KC l则有降黏作用;煤油、柴油都可使VES压裂液破胶,而且破胶后无残渣。One of the best basic formulation for Viscoelastic surfactant （VES） fracturing fluid was developed, VES 4%, additive 1.0%, the properties of which were dipticted as ： the viscosity does not change practically at 20 - 40 ℃, raised with raising temperature at 40 - 60 ℃ and droped down at 〉 60 ℃ ; the addition of NH4 Cl would increase the viscosity of the system, while KCl presented the opposite result; there was no residue produced when the system was broken down with multihydrocarbon treating agent such as kerosene and diesel.
