| 摘 要： | 石油钻杆在服役环境中要受到介质腐蚀和高温、高压等方面的影响,其受力状态十分复杂,以致失效事故频发,对失效钻杆进行失效分析与评价有助于减少或延缓钻杆失效事故的发生。介绍了石油钻杆加厚过渡区失效分析与有限元分析的研究现状。指出下一步应着重研究超长Miu长度钻杆的失效特征、失效机理与失效原因,以及采用三维有限元技术对在拉伸、弯曲、扭转复合载荷作用下的钻杆加厚过渡区进行系统的力学分析。

| Abstract: | Under multiple influences by elements like medium corrosion,high temperature and high pressure,etc.,loading state of the oil drill pipe as being operated is so complicated that failures are caused frequently. Analysis and evaluation of failure of the drill pipe are helpful to reducing or postponing occurrence of such failure. Introduced here in the essay is the current situation of research on failure analysis and FE analysis of drill pipe upset transition area. It is emphasized that the research activities... |
