New Analysis Theory and Method for Drag and Torque Based on Full-Hole System Dynamics in Highly Deviated Well
The research on calculation of torque and drag in highly deviated wells has demonstrated a significant gap against oil exploration and development; with the increasingly rigorous situation, the drill string dynamics and the contact or friction of drill pipe with borehole wall under the drill string...
