In this paper, the problem of gripping drill strings is considered to be one of the most complex and common technical issues that arise during the drilling process. The analysis of the causes and mechanism of this phenomenon is carried out, including the interaction of the drill string with the environment and the influence of local zones with increased friction forces. The main attention is paid to the development of a new mechanical method for removing entanglement based on the use of wave processes, and the dynamics of a long elastic rod representing a drill string is considered, with an emphasis on the transmission of dynamic load through the inner core.
