The invention relates to a fracturing fluid capable of resisting low pH value environment and higher salinity and a preparation method thereof. Most conventional fracturing fluid can have favorable viscoelasticity only in an alkaline environment, and the natural vegetable glue used under normal conditions is difficulty for crosslinking under acidic conditions. The preparation method comprises the following steps: uniformly mixing a viscoelastic surfactant, an acid and a dispersion pour-point depressant to form a liquid component mixture; and dissolving a water-soluble nonionic polymer thickener at normal temperature, adding the liquid component mixture, and stirring uniformly to obtain the fracturing fluid.
