Bit Selection Guide (Comparison & Recommendation)
Selection Criteria
Choose the right steel tooth bit based on 3 core factors:
- Formation Hardness: Match IADC code to formation type (soft = low IADC, hard = high IADC)
- Drilling Type: Vertical, horizontal, or directional drilling requires different bit designs
- Operating Parameters: Weight on bit (WOB), rotary speed, and mud properties affect bit performance
Selection Comparison Tabl
| Bit Size (in) | IADC Code | Best Suited Formation | Recommended WOB (kN) | Recommended RPM (r/min) | Typical Application |
|---|---|---|---|---|---|
| 8 ½ | 117 | Soft clay, mudstone | 80-120 | 80-120 | Shallow oil well, water well |
| 9 ½ | 127 | Medium-soft sandstone | 100-150 | 70-100 | Medium-depth oil well, mining |
| 12 ¼ | 137 | Medium-hard limestone | 150-220 | 60-90 | Deep oil well, directional drilling |
| 17 ½ | 147 | Hard dolomite, granite | 220-300 | 40-70 | Large-diameter surface drilling |
Selection Tips
- For soft formations: Prioritize high ROP, choose low IADC code (110-120) bits with long, sharp teeth
- For medium-hard formations: Balance ROP and wear resistance, select 120-140 IADC code bits
- For hard formations: Focus on wear resistance, use high IADC code (140+) bits with short, thick teeth
