Basalt Drilling: Effective Roller Cone Bits
Basalt poses tough challenges in water well drilling with its brittle structure.
Though slightly softer than granite, basalt’s brittleness easily cracks drill teeth. Roller cone bits excel here.
They crush rock via rolling and grind，with multiple teeth sharing impact force evenly.
Tips for water well drilling in basalt:
- Use tungsten carbide roller cones. Boost impact resistance and wear performance.
- Adopt spaced tooth layout. Balance efficiency and adaptability to complex basalt.
- Control pressure at 10-15kN, speed 80-120r/min. Pair with quality mud for cooling.
Proper roller cone bit use enhances life and speed in basalt formations.
