Soil Survey Guides Bit Choice for Water Well Drilling Rig

News 27 Views
In water well drilling rig operations, soil surveys guide soft soil bit selection critically.

 

  1. Scan with radar and test samples first. Map clay/loam depth, thickness, and water content changes.
  2. Check clay’s plasticity index—higher means stickier soil. Choose bits with larger opening angles.
  3. Note special layers: Prepare collapse-proof bits for muddy clay; enhance cuttings removal for sandy loam.

Draw detailed geological maps from surveys. They guide tools, parameters, and mud mix for water well drilling rigs, avoiding inefficiency.
