In order to increase the involvement of metallophysicists in the search for new materials and improving used ones in the field of oil-and-gas production, in the presented article, the review of available engineering tools and designs of gears, which are used for releasing of the stuck metal drilling tools, is given. A bibliographic reviewing of both state-of-the-art technologies of freeing of the stuck drilling string by means of the machine-driven methods and available mathematical models of processes of releasing of the stuck drilling tools is carried out. The physical and mathematical dynamical models of both drilling rig and engineering tools for effort to bring down problems and accidents are considered. An analysis of available methods and mathematical models for studying the operating dynamics of the metal drilling string during geological exploration work and well drilling is made.
Key words: drilling, stuck, drilling liquor, impact, vibration, drilling tool, metal drill string.
