The invention relates to high-density low-friction fracturing fluid. The high-density low-friction fracturing fluid is made of, by weight, 20-46.5% of weighting agent sodium nitrate, 0.4-0.6% of thickener hydroxypropyl guar gum, 0.4-1.0% of cleanup additive Gemini surfactant, 0.1-0.3% of pH (potential of hydrogen) modifier, 0.1-0.3% of bactericide lauryltrimethylammonium chloride or dodecyl dimethyl benzyl ammonium bromide, 0.5-1.0% of clay stabilizer quaternary ammonium salt, 0.5-1.0% of temperature stabilizer organic amine composite, and the balance water. Sodium nitrate is used for increasing weight, the density at the normal temperature can reach 1.35g / cm<3>, and the high-density low-friction fracturing fluid is long in delayed crosslinking time, low in friction, low in filter loss, high in high-temperature rheological property, and especially applicable to fracture modification of ultradeep compact reservoirs under unusual high pressure, wellhead construction pressure can be reduced remarkably. Further, the high-density low-friction fracturing fluid is applicable to massive popularization and application to mine fields, low in cost and low in stratum damage, and has wide market prospect.
