Annotation:

The article considers the process of longitudinal disturbances propagation along the drill string when drilling deviated wells using a downhole motor as well as determining the areas of possible intense vibrations of the drilling tool. The conditions of determining the optimal well profile from the point of view of minimizing intense longitudinal vibrations of the drill string and drilling trajectory are obtained.
