The invention discloses a fracturing fluid prepared from oil field produced water as well as a preparation method and application of the fracturing fluid, and relates to the technical field of petroleum exploitation. Specifically, the fracturing fluid comprises a thickening agent, a cosolvent, a deoxygenization synergist, a discharge auxiliary agent and the oil field produced water, wherein the thickening agent is xanthan gum. According to the fracturing fluid provided by the embodiments of the invention, the network molecular structure and stability of the xanthan gum are utilized, so that the temperature resistance of the prepared fracturing fluid can be improved, use of a cross-linking agent is avoided, and adverse effects of the oil field produced water on the fracturing fluid are further eliminated; the fracturing fluid can be prepared by adopting the oil produced water of different water quality, and the prepared fracturing fluid has good temperature resistance and can meet requirements of a fracturing
