Water inrush in fault zones is a
common emergency in water well drilling rig, requiring timely response. When inrush occurs:
- Stop drilling immediately to prevent worse water inflow.
- Take measures based on water volume and pressure:
- For small inrushes, increase mud density and viscosity to strengthen wall protection.
- For large inrushes, use grouting to seal fissures with cement slurry or sodium silicate.
- Drain accumulated water in the borehole promptly to protect rig equipment.
Throughout emergency response, prioritize worker safety to avoid accidents. These steps address inrush risks systematically, combining immediate actions with targeted solutions.water well drilling rig
