How deep drilling(oil, etc) avoids drill twisting on its axis? Wouldn’t kilometers long steel drills be akin to licorice?
In: 1257
the actual drill head is only at the bottom, the rest is just pipes that flush away the dirt and carry mechanical movement
The drill pipe twists slightly with resistance from the drilling, but it’s been engineered to allow for enough force before getting permanently deformed, it doesn’t really matter how long the pipe is, the force in each section is actually the same if you consider friction ***with the well walls*** negligible
