    In the drilling process, drilling Fuzheng to prevent the drill string rotating in the casing when the drill string and casing damage to casing friction. Characteristics: can be installed on any number of drill wear, and can play the role of Fuzheng and bearings to reduce frictional resistance, due to reduced friction between drill string and the casing and the consumption part of drill string torque output, thereby enhancing the the efficiency of the drilling. Drilling wear can be a "linear" and "spiral" in two forms.
