Sand Drilling Faults: Prevention for Water Well Drilling Rigs
Water well drilling rigs need fault prevention and handling in sand layer drilling. su kuyusu sondaj kulesi
Increased bit lifting resistance may mean “sand bridges” from sand buildup. Use reverse circulation immediately to flush bottom sediments.
For quicksand gushing, lift the bit fast. Increase mud density over 1.3g/cm³ to stop quicksand flow.
Tips for water well drilling rig in sand:
- Never force stuck bits. Loosen gradually with low-pressure mud circulation.
- Check bit bearing gaps regularly. Replace when exceeding limits to prevent wear.
- Keep spare bits ready. Change when cutting teeth wear over 30% to avoid accidents.
This safeguards water well drilling rigs from serious sand drilling issues.
