Study on mechanical behaviors of double shoulder Drill Pipe Joint thread
'Elsevier BV', 2019Co-Authors: Liangliang Dong, Xiaohua Zhu, Desheng YangAbstract:Double shoulder Drill Pipe Joint (DSJ) is a novel thread structure which appears in recent years. Its strength reduced efficiently while the structure design is not appropriately, for the DSJ’s mechanical behaviors weren’t well studied. In this paper a 3D whole structure finite element model of DSJ was established based on the Principle of Virtual Work, and validated the model’s computing results by experimental results. The authors analyzed the stress and strain distribution with the 3D whole structure finite element model’s computing results under torque moment, compression force, tension load, and bend moment. And then acquired the DSJ’s mechanical behaviors under each load. The research works of this paper refer accordance to recognize and design the DSJ. Key words: Double shoulder, Drill Pipe Joint, Thread, Mechanical behavio

INCREASING THE WEAR RESISTANCE OF ADAPTERS AND Drill PipeS BY ELECRTROMECHANICAL PROCESSING
Saint-Petersburg Mining University, 2018Co-Authors: Fedorov S. K., Fedorova L., Ivanova Yu. S., Voronina M., Sadovnikov A., Nikiti V. N.Abstract:The directions of the research on increasing the wear resistance of Drill Pipe locks, threaded Joints and casing Drill string have been defined: application of Drill Pipes from the nose-resistant surfacing to the lock with Russian and foreign materials (hardbanding), hardening of the surface layer of Drill Pipe locks by electromechanical processing, hardaning of the external and internal locking thread of Drill Pipes by electromechanical processing. Comparative tests of the wear resistance of various hardening materials (hardbanding) of Russian and foreign production and the Drill Pipe lock without surfacing have been made. The recommendations for increasing the wear resistance of threaded Joints by the method of electromechanical processing are developed, which determine the ways of increasing the resource and reliability of Drill Pipes and sub-assemblies, the formation of unique properties of parts, reducing the labor-capacity of manufacturing and restoring parts, increasing the efficiency of enterprises and organizations, protecting the environment and creation of competitive products. The materials of the article are of practical value for specialists of various fields engaged in the issues of increasing the reliability of technological equipment. The production success of using wear resistant surfacing technology on the body of a Drill Pipe Joint is due to the possibility of using relatively simple and mobile welding equipment, carrying out work in the places of use of a Drilling tool or temporary (permanent) production bases with a small transport arm from the field, re-depositing surfacing materials restoration of Drill Pipe locks, a wide and growing list of companies that receive accreditation for the production of these works
