Common Causes of Drill Pipe Fracture
- Excessive bending moment during reaming and pipeline pullback operations
- Deviation between actual and theoretical guide hole curves
- Irregular hole formation after reaming
- Mismatched directional drilling equipment for project requirements
- Improper reamer model selection for geological conditions
- Inadequate drill rod connection during rock reaming
- Poor drill rod selection and maintenance practices
- Excessive guide hole deviation and improper correction
- Insufficient reaming classification to accelerate construction
- Geological instability causing hole collapse and increased drilling cuttings
