Wellbore Collapse Emergency Measures-water well drilling rig
Stop drilling immediately when wellbore collapse occurs. Inject high-viscosity mud to enhance wellbore protection, and seal with backfilled clay if needed.
Quicksand and Equipment Failure Responses
For quicksand: Activate backup mud pumps, increase mud displacement and specific gravity to suppress quicksand; use grouting reinforcement when necessary.
For equipment failure: Prepare common repair tools and spare parts (bits, mud pump impellers), enabling rapid maintenance.water well drilling rig
