The invention discloses a method for preparing an efficient drilling fluid viscosity reducer by utilizing refuse leachate and application of the efficient drilling fluid viscosity reducer. The refuse leachate is subjected to concentration treatment by utilizing sulfuric acid so as to improve the structure activity of effective molecules in the refuse leachate; then an acyl chloride reaction agent is further added to react and conditions are provided for subsequent Mannich reaction and quaternization reaction, so that the molecular weight of a product is effectively improved; then prepared black loose powder is mixed and compounded with a silicon-containing compound to further improve the performance of the prepared viscosity reducer, so that the obtained viscosity reducer has high-temperature-resisting and compression-resisting viscosity reducing effects and also has salt resistance and rheological property and certain leakage reduction performance.
