Why does oil drilling choose thick-walled seamless steel tubes?

Oil is now the world's most important energy, its use is very extensive, a lot of equipment need to use oil can be normal operation. For example, we often use cars, aircraft, generators and so on. If there is no oil, then our life will be a very big change.

So now, oil drilling has been carried out in the uninterrupted. In the oil drilling time, thick-walled seamless steel pipe with this material is widely used. Many people can be more puzzled, thick-walled seamless steel pipe is hollow, its strength should be small, not as good as the use of solid steel column.
 
Indeed, the solid steel column compared to thick-walled seamless steel pipe, its strength is much higher. However, the strength of thick-walled seamless steel tubes is still very strong, the most important thing is that it has a very big advantage, that is, its vibration is very small. After all, thick-walled seamless steel pipe is hollow, in the drilling time, it can be a good transfer impact force, so that the drill to maintain a smooth, for oil drilling, is the best choice.
