1. Preparation: Before the drilling operation, the drill pipe needs to be checked and prepared, including checking the integrity of the pipe, tightening the connections, and checking the size and specifications of the pipe to ensure that it meets the requirements of the drilling operation.
2. Drilling: After the preparation is completed, the drilling rig starts the drilling operation by rotating the drill pipe and bit at the bottom of the well. During the drilling process, the drilling fluids are pumped down the pipe to cool and lubricate the bit, carry the cuttings to the surface, and maintain wellbore pressure.
3. Removal of Cuttings: As the drill bit cuts through the rock, it generates cuttings. The drill pipe is used to transport these cuttings to the surface, where they can be removed and disposed of properly.
4. Drilling Restart: After the drilling operation is completed or needs to be stopped for various reasons, the drill pipe needs to be disconnected and stored for future use. When the drilling conditions are suitable again, the drilling operation can be restarted.
These are the basic drilling operation methods of drill pipe. However, there are also various types of drilling rigs and techniques, which may require different operation methods and procedures.
