Wear-Resistant DTH Hammers for Fractured Formations: Water Well Drilling Rigs

ニュース 32 Views
The water well drilling rig uses long-stroke ball-tooth hammers for fractured rock anti-wear.

 

  1. Long stroke (60-80mm) with ball teeth: Larger broken range, 2x longer bit life than sharp teeth.
  2. Control frequency at 1000-1400/min: Reduces cylinder grinding from fractured debris.
  3. Thick cylinders (>12mm wall): 50% more wear-resistant, lasts 250hrs in 30% quartz strata.

 

Sample cuttings to pre-change bits, cutting 30% downtime. The water well drilling rig lowers pressure 10-15% to avoid jamming.
