The invention provides a weighted fracturing fluid. The weighted fracturing fluid is a liquid system prepared by using the following raw materials, by weight, 29-70.5 parts of a weighting agent, 0.2-0.8 parts of a vegetable glue thickener, 0.1-0.8 parts of a cleanup additive, 0.02-0.15 parts of a bactericide, 0.05-0.3 parts of a pH value adjusting agent, 0.1-0.7 parts of a cross-linking agent, 0.03-0.2 parts of a gel breaker and 29.5-71 parts of water. The density of the fracturing fluid at room temperature is 1.22-1.62g/cm<3> or more; the temperature resistance capability of the fracturing fluid can reach above 200DEG C; and the fracturing fluid has the characteristics of cross-linking delaying, low frictional resistance, good cross-linking performance, strong temperature and shear resistance, low filter loss, thorough gel breaking, low residue content, good expansion resistance and the like.
