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
