1 First of all, we should have a comprehensive understanding of the drilling rig, that is, maintenance:

These drilling rig instructions include butter nozzles at various parts, how long to butter, how long to change oil, how long to change filter elements, how long to change wire ropes, etc.

2, operation and walking:

The operation depends on the teacher's guidance. How much ROP, pressure and bit are suitable for each stratum? Because the stratum in each place is different and the operation method is different, you will have experience if you do more.

Walking is the most dangerous process of rotary drilling rig, so it is necessary to observe the construction site first, avoid weak points and mud pits, and prevent the rig from toppling.

3. Generally, apprentices start with the maintenance of the drilling rig and then operate on the drilling rig, so that they have a deeper understanding of the drilling rig and can solve small problems by themselves.

I hope it helps you.
