“…To explore the torsional stability of the drill string and understand the reasons for the stick-slip and possible solutions, Cunha-Lima et al [21] created one degree of freedom model to understand the stability of the drill string. Based on this model, Tang et al [22][23][24] created a mechanical model quite comparable to it to investigate the impact of drilling parameters on stick-slip vibration. Results revealed that friction coefficients, viscous damping, and rotating table velocity significantly affect the dynamics and its occurrence.…”

The critical factors that affect bottomhole stick–slip vibrations during vertical drilling operations are thoroughly investigated and analyzed in this research. Influential factors, such as rotation speed, weight on bit (WOB), bottom hole assembly (BHA) configuration, and formation properties, were studied in order to understand their part in the stick–slip phenomena. The analysis is based on a thorough review of previous research conducted on stick–slip drilling vibrations. A mathematical model was created that not only explains axial vibrations but also includes the torsional vibrations present in stick–slip occurrences, which helps with understanding the stick–slip phenomena better. This model can be used as an analytical tool to predict and evaluate the behavior of drilling systems under various operational circumstances. Furthermore, two drilling tests using a WellScan simulator were performed to validate the research findings and assess mitigation techniques’ viability. These test scenarios reflect the stick–slip vibration-producing situations, allowing us to test mitigation strategies. The finding of this study shows the effectiveness of two tactics for reducing stick–slip vibrations. First was the reduction of WOB, which successfully lowered the occurrence of stick–slip vibrations. The second was the increase in the rotation speed, which helped to control the stick–slip problem and increased the drilling speed. This study explains the complex dynamics of stick–slip vibrations during vertical drilling and offers practical, tried-and-true methods for reducing their adverse effects on drilling operations.

“…An important number of research works have been recently dedicated to the influence of the weight on the bit (WOB) on torsional vibrations; Tang et al (2017) have discussed this effect in the drill string of oil wells, and they have demonstrated that the stick-slip can be eliminated by reducing the WOB but with a time delay. In Tang et al (2015), they also highlighted the influence of increasing the rotary table speed on reducing the torsional vibrations without considering drill string stiffness. Later on, Patil and Teodoriu (2013a) have combined the two previous effects with the drill string stiffness in order to investigate the severity variations of the torsional vibration.…”

PurposeThe drill string vibrations can create harmful effects on drilling performance because they generate the stick-slip phenomenon which reduces the quality of drilling and decreases the penetration rate and may affect the robustness of the designed controller. For this reason, it is necessary to carefully test the different rock-bit contact models and analyze their influences on system stability in order to mitigate the vibrations. The purpose of this paper is to investigate the effects of rock-bit interaction on high-frequency stick-slip vibration severity in rotary drilling systems.Design/methodology/approachThe main objective of this study is an overview of the influence of the rock-bit interaction models on the bit dynamics. A total of three models have been considered, and the drilling parameters have been varied in order to study the reliability of the models. Moreover, a comparison between these models has allowed the determination of the most reliable function for stick-slip phenomenon.FindingsThe torsional model with three degrees of freedom has been considered in order to highlight the effectiveness of the comparative study. Based on the obtained results, it has been concluded that the rock-bit interaction model has big influences on the response of the rotary drilling system. Therefore, it is recommended to consider the results of this study in order to design and implement a robust control system to mitigate harmful vibrations; the practical implementation of this model can be advantageous in designing a smart rotary drilling system.Originality/valueMany rock-bit functions have been proposed in the literature, but no study has been dedicated to compare them; this is the main contribution of this study. Moreover, a case study of harmonic torsional vibrations analysis has been carried out in well-A, which is located in an Algerian hydrocarbons field, the indices of vibrations detection are given with their preventions.

“…This is an example of torsional vibration with apparent detrimental effects on the drilling process [13,17]. This movement causes premature wear of drilling tools, which considerably reduces the quality of drilled shafts [13,18] and is a source of failure [19,20]. In addition, it reduces the efficiency of drilling operations by reducing velocity of penetration [17,21,22].…”

The purpose of the experimental and numerical tests presented in this paper was to indicate a friction model suitable for simulation analyses of the impact of longitudinal tangential vibrations on stick-slip movement in sliding motion. The vibration parallel to the shift direction are forced in the contact zone of a shifted body and the base. They can cause partial or total reduction of the stick-slip phenomenon or even reduce the value of necessary drive force. The time characteristics of drive force were determined experimentally and in simulation for two cases, i.e. at a motionless or vibrating base. Simulation analyses were carried out in accordance with the described computational procedures implemented in Matlab-Simulink environment. Four models of friction were tested in the presented studies: Dahl, Karnopp, Reset Integrator and LuGre. Experimental tests were carried out on a specially designed tests stand. The Root Mean Square Error (RMSE) was used to compare the results of numerical calculations with results of experimental tests. The performed qualitative assessment and the determined RMSE values indicated that the LuGre and the Reset Integrator models ensure he best consistency of model and experimental time characteristics of the driving force.
