  • Small rotary drills are easy to operate, cutting silty sand layers via rotation with small mud pumps for circulation.
  • Portable impact drills break silty sand by impact, suitable for narrow sites.

 

  1. Medium-Depth Wells (50-150m)

 

  • Positive/negative circulation mud-flushing rotary drills address silty sand permeability and fluidity.
  • They use mud circulation to carry cuttings and stabilize the wellbore.water well drilling rig

 

  1. Deep Wells (Depth > 150m)
