  • Stop drilling immediately when wellbore collapse occurs. Inject high-viscosity mud to enhance wellbore protection, and seal with backfilled clay if needed.

 

  1. 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
