drill string vibration的意思|示意

The results show that longitudinal vibration of drill string is relative to rotary speed and weight on bit (WOB).

实验结果表明，钻柱的纵向振动主要与转速和钻压有关。

Finally, the paper introduced effective control methods of common drill string vibration and deviation problem.

最后对常见的钻柱振动和井斜问题介绍了有效的控制方法。
