Drag-Reduction Performance Evaluation of Controllable Hybrid Steering Drilling System

The excessive drag/torque and the backing pressure is an important factor that restricts the improvement of the penetration rate and the extension of the drilling in the sliding drilling process of extended-reach wells and horizontal wells. To deal with this problem, this paper developed a novel con...
