Analysis Of Oil Screen Components And Cleaning Methods

The oil screen comprises a pipe body, and the connecting and communicating through holes and through holes are provided on the wall of the pipe body and the thickness of the pipe wall. The through hole is located at one side of the inner wall of the pipe body, and the through hole is located at the outer wall of the pipe body. On the side, a casting is provided in the through hole 4, and a sieve hole is arranged in the casting. The oil screen has low production cost and simple operation. It not only ensures the permeability in actual use, but also ensures that the limited sand control can meet the requirements of rock sand particles below 0.2mm. Suitable for limited sand control such as oil wells, wells, and brine wells.

The automatic cleaning device for the inner surface of the oil screen comprises: a dresser that is inserted into the oil screen and moved relative to the oil screen; the drive mechanism that drives the dresser to reciprocate along the length of the oil screen; is connected to the dresser and the drive The core rod between the mechanisms; the water supply and air supply part for scouring and air drying the inner surface of the oil screen during the dresser cleaning process. The utility model is to clean the oil screen of 10 meters to 13 meters, and completely remove the residue on the inner surface of the high speed rotating petroleum sieve tube by using the relative movement between the rotating oil screen tube and the reciprocating feed grinding device. The hollow core rod of the utility model serves as a passage for the water supply pipe and the gas supply pipe, and can not only cool the cutter but also use the high pressure water to clean the inner surface of the oil sieve pipe, so that the quality of the oil sieve pipe cleaning meets the standard requirements.
