PDC drill bit is very specific to the formation. In directional construction, as the strength of the formation increases, the tool face changes greatly. The PDC drill bit mechanical drilling speed is significantly higher than that of the roller cone bit, and it can be achieved with a smaller WOB. The drilling speed of the roller cone bit under the large drilling pressure, and the pump pressure lower than that of the roller cone bit, can achieve a higher drilling speed at a higher speed, the load
