Stick slip vibrations in drilling: modeling, estimation, avoidance

Résumé

This paper presents a field-validated torsional model for the drill string dynamics and different algorithms for estimating the friction factors along the drill string and bottom hole rotational velocity. These friction terms characterize the interaction between the drill pipe and the wellbore walls (Coulomb source terms) within the curving wellbore. This information is essential to designing the next generation of stick-slip mitigation controllers, developing real-time wellbore monitoring tools, and enabling effective toolface control for directional drilling.
