The utility model relates to an erosion experiment device for a sand control screen pipe. The erosion experiment device comprises a stirring mechanism, a pumping mechanism and at least one group of experiment units, the experiment unit comprises an experiment pipe, a stirring mechanism and a pumping mechanism, the experiment pipe is connected to form a circulation loop, and a to-be-tested sand control screen is installed in the experiment pipe. The stirring mechanism mixes and stirs sand and water, and the pumping mechanism pumps the sand-containing fluid stirred by the stirring mechanism intothe experiment pipe, erodes the sand control screen to be detected, and returns the sand-containing fluid to the stirring mechanism after the sand-containing fluid passes through the sand control screen to be detected. And a pressure measuring assembly for measuring pressure and a flow measuring assembly for measuring flow are arranged on a pipeline, between the pumping mechanism and the experiment pipe, of the circulation loop. The circulation loop is provided with pressure difference measuring assemblies used for measuring the pressure difference between the two sides of the to-be-measuredsand control screen in the experiment pipe and the pressure difference between the upstream of the experiment pipe and the interior of the experiment pipe so as to obtain the state of the to-be-measured sand control screen after being eroded by the sand-containing fluid according to the pressure, the flow and the pressure difference.
