Advantages:
1. Exceptional Gauge Protection:
It drastically reduces gauge wear, maintaining full hole diameter and ensuring drilling accuracy.
2. Extended Bit Life:
The hardfacing shields the bit body from abrasive formation, significantly increasing its operational lifespan.
3. Enhanced Steering Stability:
By preserving the bit’s profile, it provides consistent directional control and reliability for complex well paths.
4. Superior Erosion Resistance:
It protects critical areas from the destructive scouring of high-velocity drilling fluid and cuttings.
5. Improved Cost Efficiency
The combination of longer life and consistent performance reduces trips and downtime, lowering the overall cost per foot.
Applications:
Hardfaced PDC bits are critical equipment in geothermal exploration, where they withstand extreme heat and highly abrasive volcanic formations.
In civil engineering and infrastructure projects, they excel at drilling through challenging mixed ground and reinforced concrete for foundation piling.
The mining exploration industry relies on them for their durability and longevity in penetrating hard rock layers for mineral sampling and blast hole drilling.
Furthermore, they are indispensable in geological exploration for obtaining intact core samples from deep, variable strata. Their robust wear resistance makes them the preferred choice for these demanding sectors, ensuring high efficiency.
