The wear and tear of casing and the higher drilling torque has become a serious problem
encountered when drilling the high angle deviated well, the horizontal well and the deep well. The drilling torque reducing tool can be used to solve these problems very well.
Technical Features
1. Optimally designed tungsten carbide plain bearing is lubricated with the drilling fluid
during the drilling process.
2. This tool is designed for reducing the occurrence rate of the drilling problems caused by the excessive drilling torque when drilling the high angle deviated well, the horizontal well and the
ultra-deep well.
