Drill String Mechanics

Drill string mechanics involve understanding how the long column of connected pipes, called the drill string, behaves as it rotates and moves down into the earth during drilling. It transmits torque to turn the drill bit, carries drilling fluids, and withstands forces and pressures. Managing its mechanics is crucial for preventing issues like buckling, vibrations, or unexpected stress, which can cause equipment failure or drilling delays. Essentially, it’s about ensuring the drill string functions smoothly and safely as it helps extract underground resources.
