Depth Adaptability: DTH Hammers for Deep Water Well Drilling Rigs

The water well drilling rig DTH hammer handles deep wells well, unlike traditional rigs.

 

  1. Efficient at 200m: High-pressure air clears cuttings fast. Works with casing for non-stop drilling.
  2. Stable at 300m: A mine used 1.8MPa hammers. Drilled granite at 0.8m/h, with <15% pressure loss.
  3. Handles ultra-deep wells (>500m): Uses staged relays, with pressure 补偿 every 200m. Avoids torque issues.

 

Its sealed drill pipe joints keep impact frequency over 1200 times/min. The water well drilling rig reaches greater depths reliably.
