MATHEMATICAL MODEL, THREAD FORMING, HERMETIC HIGHTORQUE CONNECTION, SCREWING, UNSCREWING, COATING, FRICTION HARDENING, PLASMA ELECTROLYTIC OXIDATION, SURFACING, FACING, DAMPING DEVICES, The object of research is the design and technology of manufacturing, protection and repair of threaded connections of responsible purpose, in particular tapered thread tool-joint with improved operational characteristics. The purpose of the work is to develop and provide practical recommendations for the creation of threaded connections of a responsible purpose with increased mechanical, hermetic and anti-corrosion characteristics, as well as the design of damping devices and devices for repair work, based on the development of models of shap-criating, strengthening, 3D models of the structures of nodes and devices threaded connections in wells. Research methods — a systematic approach, methods of mathematical and computer modeling, as well as conducting a laboratory experiment. Analytical assurance of the accuracy of thread shap-criating in the process of its manufacture with a high-performance tool has been developed, which makes it possible to significantly increase the accuracy, screw-ability and tightness criteria of tapered thread tool-joint with a triangular or trapezoidal profile. 3D models of high-moment threaded connections have been developed. The processes of friction hardening and plasma electrolytic oxidation of threaded surfaces are simulated. A new approach to carbide setting of drill thread tool-joint is proposed. Also developed is the design of a damping device to reduce the load on the threaded connections and devices to ensure the effective unscrewing of the drill pipes in the well during the repair is developed. Practical recommendations on the application of scientific and technical developments of the project, which will provide an opportunity to increase Product Description popup.authors Burda Myroslav Yo.
