“…Torsional vibration is a problem in drill string dynamics, especially when its length reaches thousands of meters. In some conditions, the lateral and axial vibrations are small, and the torsional vibration is the main concern Ritto TG et al (2017); it might lead to stick-slip oscillations Kyllingstad A and Halsey GW (1988); Leine RI et al (1998); Tucker RW and Wang C (1999); Richard T and Detournay E (2004); Khulief YA et al (2007); Kreuzer E and Steidl M (2012); Patil PA et al (2013); Hong L et al (2010). In this severe conditions, the bit sticks (zero speed) then slips (high speed), and that might cause, for instance, measurement equipment failure, low rate of penetration, bit damage, and fatigue Wu X et al (2012).…”

This paper aims at constructing a stochastic model for the hysteretic behaviour of the nonlinear bit-rock interaction of a drill string under torsional vibrations using field data. The proposed model takes into account the fluctuations of the stick-slip oscillations and the hysteretic effect due to the nonlinear bit-rock interaction observed during the drilling process. These fluctuations are modelled by introducing a stochastic process associated with the variations of the bit-rock interaction during the drilling. The parameters of the stochastic model are calibrated with field data. Finally, independent trajectories of the proposed stochastic model are generated and used to simulate the stochastic response of the drill string torsional dynamics in presence of random bit-rock interaction. The stochastic model is then used to estimate statistics on the stability of the drill string.

“…In addition to all control methods, some attempts have been made toward using observer/estimator-based controller in order to overcome the limitation of accessing downhole real-time measurements. For example, Hong et al [34] presented simulation results using Kalman estimator to control the stick-slip vibration. Due to the great deal of uncertainties in the model parameters and changing conditions during drilling, any theoretical work must be supported by realistic experimental studies, which are rare.…”

We investigate experimentally and numerically suppression of drill-string torsional vibration while drilling by using a sliding mode control. The experiments are conducted on the novel experimental drill-string dynamics rig developed at the University of Aberdeen (Wiercigroch, M., 2010, Modelling and Analysis of BHA and Drill-string Vibrations) and using commercial Polycrystalline Diamond Compact (PDC) drill-bits and rock-samples. A mathematical model of the experimental setup, which takes into account the dynamics of the drill-string and the driving motor, is constructed. Physical parameters of the experimental rig are identified in order to calibrate the mathematical model and consequently to ensure robust predictions and a close agreement between experimental and numerical results for stick–slip vibration is shown. Then, a sliding mode control method is employed to suppress stick–slip vibration. A special attention is paid to prove the Lyapunov stability of the controller in presence of model parameter uncertainties by defining a robust Lyapunov function. Again experimental and numerical results for the control cases are in a close agreement. Stick–slip vibration is eliminated and a significant reduction in vibration amplitude has been observed when using the sliding controller.
