Key words: well drilling; resonance; fluctuations; controller.

Based on analysis of accelerometer and gyroscope data, which valuate (in real time) the dynamic component of drill string in the process of hole deepening and also the specifications of equipment drilling rig – we are suggest the algorithm, which prevents resonance the bottom of the drill string by the prognostication and control of forced oscillations and characteristic oscillation also by the changing of rotation frequency and weight on bit (WOB).
