Steps for removing internal burrs from the oil screen: slide the structural pipe to the deburring machine, and remove the screw protectors on both sides; blow out the iron pins in the pipe with compressed gas; short-circuit the casing to indicate that the gas motor supply of the deburring machine is turned on. Press the air button to check whether the length of the milling cutter is long enough and whether it is sharp; turn the radial movement button of the cutter bar, shake the air motor button when the milling cutter extends into the pipe, and the milling cutter will run at high speed immediately, and then adjust the radial movement rate of the milling cutter. Until the milling cutter passes through all the holes in the tube, turn the cutter bar in the opposite direction and move the button radially to move the milling cutter back until the air motor button exposes the end of the tube, stop the air motor immediately, and the milling cutter is still moving radially, when it reaches the start and end parts, Turn the shank to move the button radially to the end position.

Steps for removing the outer burrs of the oil screen: use a flat file to remove the burrs with the orifice higher than the outer edge of the pipe; use a small round file to remove the burrs on the opposite side of the punch; remove the screw protectors on both sides with compressed gas Blow out the iron pins in the pipe, install the screw protectors on both sides, and transfer to the next process.

Features of oil screen: firm structure, high temperature resistance and corrosion resistance, good physical properties, long service life, safe and reliable. The surface layer of the filter tube is neat and smooth, the tube body has high linearity, firm structure, high porosity and precise gap specifications. Casing Shorting Wholesale pointed out that it is mainly used in fine sand and siltstone formations in motor-driven wells. The trapezoidal wire filter tube is easy to backwash, has a long service life, is safe and reliable, and has an overall low cost. Filter tubes with higher porosity are more suitable for constructing high-efficiency oil, water and gas wells. Low-cost operation and high porosity filter tubes are more beneficial to the infiltration of surface water.
