Solving Tooth Breakage in Tricone Drill Bits
Root Causes of Tooth Breakage
Excessive Weight on Bit (WOB)
Overloading beyond design specifications induces high-stress fractures, particularly in hard/heterogeneous formations where aggressive drilling accelerates wear.
01
Fractured Formation Drilling
Irregular cracks and abrasive particles in fractured strata create uneven loading, causing localized stress concentration and tooth failure.
02
Suboptimal Tungsten Carbide Insert Selection
Insufficient hardness or wear resistance for complex geology leads to rapid insert degradation and breakage, reducing drilling efficiency and bit life.
03
Cone Interference
Poorly calibrated cone clearances increase collision risks during operation, directly contributing to tooth damage.
