The invention relates to a high-pressure filter pressure reducer which is characterized by comprising a closed box body. A hollow cavity is arranged inside the closed box body. A pore plate is slantly arranged inside the hollow cavity of the closed box body. The hollow cavity is divided into a front filter cavity and a back filter cavity. A high pressure water inlet and a low pressure water outlet are formed in the wall of the closed box body. The high pressure water inlet is communicated with the front filter cavity. The low pressure water outlet is communicated with the rear filter cavity. The high-pressure filter pressure reducer is ingenious and reasonable in structural design, it is ensured that particulate matter contained in a high pressure water well can be effectively filtered out, pressure can be reduced under the specific flow capacity, deslagging is convenient, and safety of an oil field high pressure well washing device is improved.
