Depth-Based Bit Choice: Gravel Drilling Rigs

Water well drilling rigs need depth-specific bits for varying gravel layers. water well drilling rig

 

Shallow gravel (0-30m): use lightweight hammers. 100-150J impact works with small rigs.

 

Medium depth (30-100m): switch to heavy roller bits. 25mm+ body handles higher pressure.

 

Tips for water well drilling rig depth selection:

 

  1. Ultra-deep gravel (>100m) needs water-pressure sealed bits. Double-seal bearings.
  2. Increase bit strength with depth. Use S135 drill pipes below 150m.
  3. Match rig power to depth. Ensure enough impact and torque for bits.

This optimizes performance across all gravel depths effectively.
