石油和天然气运营商在处理更复杂的长水平井时，追求速度和效率，这导致振动事件频发，这些振动事件可能会损坏重要的井下工具，从而导致钻井作业中断。其中一种代价高昂的现象被称为扭转振动，它是由波动扭矩引起的扭转运动引起的。

让钻井体验更顺畅的关键在于保持钻头和钻杆在底部钻具组合(BHA) 上方同步旋转。如果它们以不同的速度旋转，就可能发生扭转事件，使钻井体验从海滩男孩 (The Beach Boys) 的“震颤”转变为杰瑞·李·刘易斯 (Jerry Lee Lewis) 的“天摇地动” (Whole Lotta Shakin)，速度之快甚至超过了起钻速度。

你拧干过湿毛巾吗？这就是施加扭转振动的一个例子。你在毛巾两端施加反向扭转力，使其扭转并振动。

il and gas operators’ pursuit of speed and efficiency when it comes to more-complex, long lateral wells has given rise to vibrations events that can sideline drilling operations by damaging vital downhole tools. One of the costly phenomena is called torsional vibration, which is caused by a twisting motion because of fluctuating torques.

The key to smoothing out the drilling experience is to keep the bit and drillpipe above the bottomhole assembly (BHA), spinning in unison. If they start spinning at different speeds, a torsional event can occur that can take the drilling experience from the The Beach Boys’ “Good Vibrations” to Jerry Lee Lewis’ “A Whole Lotta Shakin’ Going On” faster than you can trip out of the hole.

Have you ever wrung out a wet towel? That’s an instance of applied torsional vibration. You applied opposing twisting forces to the towel’s ends, causing it to twist and vibrate.
