Key Features
- Crawler chassis for easy movement and fast speed
- Hydraulic oil pressure feed device improves drilling efficiency
- Pressure gauge displays bottom hole conditions
- Hydraulic cylinder controlled drill mast enhances operation efficiency
- Diesel engine with electric starter reduces labor intensity
Drilling Process
- Drill holes, take samples, and create drilling profile structure diagram
- Backfill with 1.8-2.0 m3 of siliceous sandy pebble filter material (20-40mm particle size)
- Ensure well pipe is vertical and polyethylene plastic pipe wall is 8mm thick
- Use drilling filter with 18-20mm holes and at least 25% drilling rate
- Secure well pipe with overlapped joints and 25 mesh filter screen wrapped in 2 layers
Drilling Process Considerations
The drill bit quality directly affects water well drilling efficiency and quality. Proper selection and operation are crucial for optimal performance.
- Replace central drilling tool after structure drilling, clean hole bottom, and lift drilling tool with appropriate force
- Monitor casing follow-up and maintain hole cleanliness during drilling
- Use air pressure to clean hole if rock slag affects eccentric bit retraction
