钻井过程专业英语怎么说
Drilling process refers to the operation of creating a hole in the ground using a drilling rig. The process involves several stages, starting with the drilling rig being set up at the drilling site. A drill bit is attached to the bottom of a drill string, which is then rotated and pushed into the ground to break up the rock and soil. The drilling fluid, or mud, is pumped down the drill string to cool the bit, remove cuttings, and maintain pressure. Once the hole reaches the desired depth, it may be lined with steel casing to provide structural support and prevent collapse. The drilling process is crucial in extracting minerals, oil, and gas from beneath the Earth's surface.
