During the drilling process, between the drilling bit that ruins the rock in the bottom-hole and the energy source located on the ground surface is the drillstring that has certain length and small cross cuts that define the dynamics of the drilling bit work. Along with the development of science, for optimization of drilling processes were developed and continue to be elaborated mathematical models that use empirical dependencies based mainly on laboratory data which are very far away from the real conditions of well construction and fail to take into account all the peculiarities of this process. Thus, the management of the drillstring dynamics related to an increase in the effectiveness of deep directional and horizontal wells drilling process through the minimization of torsional and longitudinal Iow frequency vibrations of drilling instrument is a matter of topical interest nowadays.
