Product Information

In rotating drilling process, the rotating power of drill bit is from rotary rig platform or top-drive equipment through the drill stem. In the process of directional, drilling because of the friction between drill stem and well wall or drill stem and casing, it is difficult to transfer the rotating power, especially in horizontal well. Because of the loss of torque, it will effect the rig efficiency and reduce the rig drilling power. The friction between drill stem and well wall or drill stem and casing will reduce the life of drill stem and casing, also the well wall will become irregularity. Because of the loss of passing torque, it should increase the torque load of drill stem in order to keep the drilling torque on bit. So it will reduce the drill stem's safety factor. All these will effect the safety, quality and rapid drilling.

Wear sub can valid resolve the above mentioned problems in the process of oil and gas drilling. It can reduce the drilling torque and friction between drill stem and casing by rotating drilling. So it can protect the casing and drill pipe.
