摘　　要：石油钻杆在使用过程中与岩壁和泥浆摩擦会发生磨损,钻杆接头比钻杆要粗,因此钻杆接头台肩面更容易磨损。在钻进过程中通过接单根来延长钻杆,钻杆螺纹不停地拧紧卸下,也易磨损或局部损坏。通过对钻杆的维修可以延长使用寿命提高重复利用率,节约成本。本文提出一种钻杆接头螺纹的数控加工修复方法及修复过程中的对刀方法,通过对127mm钻杆NC50接头螺纹进行编程,然后利用数控机床加工完成了钻杆接头螺纹的修复。Drill pipe will wear and tear against the rock wall and mud.The drill pipe joint is thicker than the drill pipe,so the shoulder surface of the drill pipe joint is more prone to wear and tear.During the drilling process,the drill pipe is extended by connecting a single piece,and the threads of the drill pipe are constantly tightened and removed,which can also cause wear or local damage.By repairing drill pipes,the service life can be extended,the reuse rate can be improved,and costs can be saved.This article proposes a CNC machining repair method for drill pipe joint threads and a tool alignment method during the repair process.By programming the 127mm drill pipe NC50 joint thread and using a CNC machine tool,the repair of the drill pipe joint thread is completed.
