详细介绍
倒扣器是一种动力换向工具,通过它可以把上部钻杆的右旋运动变为下部工具的左旋运动,从而实现倒扣作业。
该工具的优点:
1.只用一套正扣钻杆就能完成倒扣作业,在没有钻杆的现场,可以用油管倒油管。
2.输入扭矩小于输出扭矩,作业中钻杆的扭矩变形小,反弹力也小。这对延长钻杆的使用寿命保证作业安全均有好处。
3.在倒不开、提不动的特殊情况下,可以随时退卡提出工具。
Back-off Tool is a kind of power reversing tool, through which the right rotation of the upper drill pipe can be changed to the left rotation of the lower tool.
Advantages:
1. Reverse operation can be completed with only one set of positive drill pipe, and in the site without drill pipe, you can use tubing to back-off the tubing.
2. The input torque is less than the output torque, the torque deformation of the drill pipe is small, and so is the rebound. This is beneficial to prolong the service life of drill pipe and ensure the safety of operation.
3. In the special case that cannot be opened or lifted, this tool can be returned at any time.
