Web25. nov 2024 · Abstract. Slide drilling is widely used in directional drilling because of its lower cost, but the tool-face adjustment during the drilling process is almost completed by the driller, and the automatic control has not yet been realized. The main difficulty is that the drill string system has a large amount of contact and friction with the wellbore. Moreover, … WebThe toolface angle is the angle made by the tool face on a horizontal plane with respect to the magnetic North. The angle is measured in a plane perpendicular to the drill string axis between a fixed reference and a reference direction on the drill string. For vertical wells, North is the fixed reference and the angle is called the magnetic ...
