The invention provides a fracturing fluid. The fracturing fluid comprises a base solution and a crosslinking agent, wherein the base solution is prepared from components in percentage by weight as follows: 0.3%-0.4% of a thickening agent, 0.2%-2% of a sulfur remover, 0.1%-0.2% of a shielding agent, 0.1%-0.2% of an environment-friendly bactericide, 0.3%-0.5% of a clay stabilizer, 0.3%-0.4% of a discharge aiding agent and the balance of water; the mass ratio of the base solution to the crosslinking agent is 100: (0.3-1). The fracturing fluid has unique salt resistance, can meet rapid crosslinking and sand carrying of highly-mineralized production water, has good temperature resistance and shear resistance as well as high sand-suspending performance, realizes thorough gel breaking and has small influence on fracture conductivity, meanwhile, the water resource utilization efficiency is improved, and the reservoir improvement requirement at the temperature of 100 DEG C or below can be met.
