Characteristic
◆ Select the appropriate tooth profile and bearing structure based on the characteristics of the drilling rig and different geological conditions.
◆ The palm tip is widened and thickened with alloy, and the palm back is inlaid with anti wear alloy to reduce wear. Hydraulic rock breaking. Smooth slag discharge to reduce rock slag accumulation.
◆ Welding process to prevent welding overheating. The guide belt design of the drill bit body has good guiding effect, making the reamer smoothly contact the wellbore.
◆ Reasonably design the guiding belt of the drill bit body, with good guiding effect, so that the reamer can smoothly contact the wellbore wall and reduce the tendency of pipeline trajectory variation.
