What are the methods for dealing with stuck water well drilling rig tools
1. Lift the drilling tool up and down repeatedly:
Lift and turn the drilling tool in small increments to try to loosen it.
2. Flush the borehole:
Increase the flow of drilling fluid to remove rock chips or collapsed material from the stuck location.
3. Use shock:
Release the jammed drilling tool by shocking.
4. Replenish casing:
If the collapse is serious, use casing to protect the well wall to avoid the drilling tools being stuck again.
5. Reasonable control of drilling parameters:
Optimize drilling pressure, rotational speed and feed rate to avoid excessive impact.
6. Keep the hole clear:
Remove rock chips in time to prevent blockage.
7. Monitor the condition of the well wall:
Take reinforcement measures (e.g. casing protection) for loose formations or formations prone to collapse.
