Three-dimensional mechanical properties analysis and fatigue life prediction of G105 drill pipe
Abstract:G105 drill pipe has been widely used in drilling construction, such as mine exploration, water exploration, and gas extraction. However, the service life of the drill pipe is lower than its de-sign life. The drill pipe is the most vulnerable component within the overall structure of the drilling tool due to its exposure to cyclic axial tension, torsion, and bending forces. Taking the G105 drill pipe as the research object, the mechanical property parameters and fatigue S-N curve of drill pipe material were tes… Show more
