The invention relates to a high temperature resistant salt-resistant no-solid-phase environment-friendly well completion drilling fluid, which can effectively overcome the shortcomings in the performance and the application of the prior well completion drilling fluid, in particular can avoid damage to stratum, and can meet the strict requirements for environment protection. The invention has the technical proposal that the well completion drilling fluid is made up from water, formate, viscosity increaser, filtration loss reducing agent, oil layer protective solute and polymeric-alcohol collapse preventing agent. The well completion drilling fluid is ensured to contain no solid-phase component, reduces the damage to the stratum greatly, has fine structural components, not only optimizes the overall performances of the system, but also improves the stability of heat resistance and salt resistance of the system. The constituents adopted by the invention are all water-soluble substances, the pollution on the environment caused by emissions is reduced, the system also can be recovered and recycled, and high-priced fluid preparing cost can be reduced greatly.
