Bit Skills: Water Well Drilling Rigs in Different Sands
Water well drilling rigs need tailored bit operations for various sand layers. water well drilling rig
In fine sand, keep steady high speed and low pressure. 80-100 rpm, 5-8 tons—avoid sand hole from over-disturbance.
For medium sand, use “gradual pressurization”. Start at 5 tons, add 1 ton every 3m, max 12 tons.
Tips for water well drilling rig bit operations:
- Slow to 40-60 rpm in coarse sand. Increase pressure to 10-15 tons for better breaking.
- Drill slowly in quicksand with “drill-retreat” pulses. Feed ≤50cm each time, boost mud flow.
- Watch pressure gauges closely. Sudden drops may mean quicksand influx.
These skills optimize performance for water well drilling rigs across all sand types.
