To the study of dynamic stability of the drill string during drilling

Ukhta State Technical University, Ukhta

Summarized the reasons for the violation of the dynamic stability of the drill string in the drilling process. The conditions for vibration-free running of the drill string. It is shown experimentally that oscillatory processes in the electrical drive–drill string adequately describes the two-mass model, which allows the development of the structure of electromechanical systems effectively damping oscillations of the drill string due to the capabilities of the drive.
