1. After the drill bit of the hydraulic well drilling rig is
drilled into the structure, the center drilling tool needs to be
replaced in time. First, the bottom of the hole needs to be
cleaned, and then the residue at the bottom of the hole needs to be
blown clean. After the bit stops rotating, drill out the bit in the
hydraulic well drill. It is most suitable when the lifting force is
slow enough to lift the bit.
2. Drilling process summarizes the bit of hydraulic well drilling
rig. It is also necessary to pay close attention to the follow-up
conditions of casing, understand the specific situation of drilling
in time, clean up the drilling in time, and drill the bit on the
well drilling rig. Strong lifting is prohibited in this process.
