The utility model belongs to the technical field of petroleum industry machinery, sand control screen in concretely relates to oil well operation. A but sand control screen of regulation and filtration particle diameter, includes that outer screen and inlayer screen pipe are hollow nos round -ended cylinder and describe from outer measure -alike outer screen and the inlayer screen pipe that sets gradually in to, outer screen and inlayer screen pipe rotate to be connected, be equipped with a plurality of outer hole holes on the outer screen, the department that corresponds of inlayer screen pipe is equipped with a plurality of interior holes, and the size in interior hole and outer hole hole is different, the interval in two outer hole holes that each line is adjacent is greater than the width of interior hole. The utility model discloses nexine screen pipe and outer screen rotate relatively, and different with interior hole size because of the outer hole hole, when rotating, the overlap section of outer hole hole and interior hole is constantly changeable, consequently, but the size of regulation and filtration particle diameter.
