The invention relates to a clean fracturing fluid and the application thereof, and the fracturing fluid comprises the components based on the parts by mass: 50-80 parts of thickening agent, 10-35 parts of salicylate and 2-5 parts of gel breaker. The clean fracturing fluid is used for fracturing oil field; in the application site, the components are mixed according to the parts by mass to prepare aqueous solution with the mass percent of 2-6% and evenly stirred, and then is thrown into an oil well together fracturing propping agent. The fracturing propping agent of the clean fracturing fluid is even in dispersion and thorough in gelout.
