When drilling holes in the operation breed destructive tool and drill string are destroyed as a result of elastic vibrations and static and external loads. Therefore, the actual problem is the study of the spectrum of natural vibrations of the drill string, depending on its layout (number of sections), the total length of the sections, the cross-section of drill pipe. The development of methods for determining the frequency range for each configuration of the drill string will predict the emergence of high-profile areas. The development of methods for determining the frequency range for each configuration of the drill string will predict the emergence of high-profile areas. The use of the boring tool for these unwanted frequencies, but in case of accidents (stuck drill string) vibration method should be adjusted exactly to the resonance frequency.
