Hole Wall Treatment & Bit Choice for Water Well Drilling Rig

Balita 40 Views
In water well drilling rig operations, post-drilling wall treatment links closely to bit selection.

 

  1. Clay holes from scraper bits need high-pressure grouting to fix cracks.
  2. Regular walls from spiral bits allow direct well pipe installation easily.
  3. Adjust completion by bit type: Larger filters for sparse-tooth bits; simpler cleaning for anti-stick bits.

Choose bits considering follow-up needs. This connects drilling and completion smoothly, cutting costs for water well drilling rigs.
