The influence of working environment on fatigue of oil drill pipe joints


release time:2024-11-15

source: network

        The working environment has a significant impact on the fatigue characteristics of oil drill pipe joints:
1. Cyclic load action: During the drilling process, the drill pipe joint is subjected to various cyclic loads such as tension, compression, bending, torsion, and vibration for a long time. These cyclic loads can cause alternating stresses inside the drill pipe joint, leading to fatigue failure.
2. Drilling fluid corrosion: Drilling fluid may contain various corrosive substances that can corrode the surface of drill pipe joints. Corrosion can reduce the material strength of drill pipe joints, thereby exacerbating the occurrence of fatigue failure.
