| 摘 要： | 在钻井过程中，钻铤螺纹承受的载荷非常复杂，常发生失效事故。通过对钻铤螺纹失效问题的深入分析，找出了钻铤螺纹失效的主要原因，提出了采用双台肩螺纹接头、数字型螺纹和使用成型梳齿刀具加工螺纹等3种解决措施。重点对双台肩螺纹接头进行了分析计算，证明了采用双台肩螺纹接头解决钻铤螺纹失效事故的有效性。

| Abstract: | In drilling process, drill collar thread bear complex load, failure accidents occur frequently. This thesis will further analysis these problems and the main reasons causing drill collar thread failure, three measures have been proposed, such as using double shoulder screwed sub, NC thread and forming tool process thread, then putting emphasizes on anglicizing and calculating double shoulder screwed sub, approved the effectively of using double shoulder screwed sub resolve drill collar thread failure. |
