发明名称 Optimized Rotation of a drill string during a sliding mode of directional drilling
摘要 An example method for optimized notation of a drill string coupled to a drill bit and disposed within a borehole may comprise determining an angular velocity of at least part of the drill string. An angular velocity threshold to avoid static friction may also be determined. Additionally, a minimum input torque to apply to the drill string to maintain the angular velocity at or above the angular velocity threshold may be determined. The method may further include generating a control signal to a top drive motor based, at least in part, on the minimum input torque.
