Annotation:

During rotary drilling with certain combinations of operating parameters (P0 – axial load on the bit; n0 – rotor rotation speed) and mechanical characteristics of the "drill string–bit–bottomhole" system, both torsional self-oscillations and longitudinal resonance oscillations can occur in the drilling tool. They have a very negative impact on both the efficiency of rock destruction and the durability of the drilling tool. The article deals with the problems of minimizing low-frequency longitudinal resonant vibrations of the drill string. The conditions for the occurrence of longitudinal resonant oscillations in the zones of torsional self-oscillations and uniform rotation of the drilling tool as well as relations that provide the boundaries of the intervals in which the resonance valuesof the well depths are located, are obtained.
