摘要
在井斜角或方位角变化大、井眼缩径以及钻具绕井眼轴线公转的情况下,钻具与井壁之间磨损严重,并使钻具产生巨大的反扭矩。研制了旋转式防磨减扭接头,钻井时将该工具接于钻具组合中,既防止钻具与井壁之间的磨损,又减小钻具承受的反扭矩,现场应用效果良好。
If the drift azimuth is big,well bore shrinkage or the drill is rotating around the hole axis,the wear between the drill string and the borehole face is big,and it makes the drill string produce the huge opposing torque.The rotary wear fanning reducing torque adapter was developed,the tool is connected by the drill string while the well is drilling,which not only reduces the wear between the drill string and the borehole,but also reduces the opposing torque.It is ideal in practical application.
