  The oil screen pipe includes a pipe body. On the wall of the pipe body and through the thickness of the pipe wall, there are connected and communicated through holes and through holes. The through hole is located on one side of the inner wall of the pipe body, and the through hole is located on one side of the outer wall of the pipe body. There is a casting in the through hole 4, and the casting is provided with a screen hole.

  The production cost of the oil screen pipe is low, and the operation is simple. In practical use, it not only ensures the permeability, but also ensures that the limited sand control can meet the requirements of rock sand particles below 0.2mm. It is suitable for limited sand control in oil well drilling, water well and brine well.

  The automatic cleaning device for the inner surface of the oil screen pipe includes: a grinding device which probes into the oil screen pipe and moves relative to the oil screen pipe for cleaning; a driving mechanism which drives the grinding device to move back and forth along the length direction of the oil screen pipe; a core rod connected between the grinding device and the driving mechanism; and a water supply and gas supply part which scours and dries the inner surface of the oil screen pipe during the cleaning process of the grinding device.

  The utility model is to clean the 10-13-meter oil screen pipe, and thoroughly remove the residues on the inner surface of the high-speed rotating oil screen pipe by using the relative motion between the rotating oil screen pipe and the reciprocating feed grinder. The hollow core rod of the utility model is used as the channel of the water supply pipe and the gas supply pipe, which can not only cool the cutter, but also use the high-pressure water to clean the inner surface of the oil screen pipe, so that the cleaning quality of the oil screen pipe can meet the standard requirements. High pressure gas can blow the pipe dry at any time to prevent corrosion.
