作者试图从改变钻杆连接方法出发,寻找解决钻杆上卸扣费时费力问题的新途径,设想把锥管螺纹传递扭矩、承受轴向载荷及密封等三项功能,分别改由螺旋面牙嵌、带有纵向切槽的梯形螺纹及密封胶囊承担,并用“磁牙”防止自动卸扣和用于倒转钻具。作者认为,改用这种快速钻杆接头之后,上卸扣所用时间和力矩仅为现有接头2％和0.5％左右,井口只需一人操作。 The author tries to find out a new way to solve the time-consuming and labor-consuming problem of shackle on drill pipe by changing the connection method of drill pipe. Imagine the three functions of taper pipe thread transmitting torque, bearing under axial load and sealing, , Trapezoidal threads with longitudinal grooving and sealing capsules, with “magnetic teeth” to prevent automatic shackles and for inverting the drill. The authors argue that the time and torque used on the shackle were only about 2% and 0.5% of the existing joints after switching to this quick-action drill pipe joint, and that the wellhead needed only one person to operate.
