Characteristics of Composite PDC Cutting Teeth in Oil Drill Bit Components

Among the oil drilling components, the composite PDC (Polycrystalline Diamond Compact) cutting teeth have remarkable features.

PDC cutting teeth are made of diamond micropowder and cemented carbide matrix sintered under high temperature and high pressure, with extremely high hardness and excellent wear resistance. This enables the PDC cutting teeth to effectively resist rock abrasion during drilling, maintain sharp cutting edges and extend the service life of the drill bit.

PDC material has good thermal stability and can maintain stable performance under high temperature environment. In the oil drilling process, the drill bit will come into contact with high-temperature rock and mud, and the PDC cutting teeth can resist the erosion of high temperature to ensure the stability and efficiency of drilling.

Although PDC cutting teeth are known for their high hardness, the underlying cemented carbide matrix provides PDC with excellent impact toughness. This enables PDC cutting teeth to withstand the shock and vibration of rock and maintain stable cutting performance under complex geological conditions.

The hardness and wear resistance of PDC cutting teeth make their cutting efficiency much higher than that of cutting teeth made of traditional materials. In the drilling process, PDC cutting teeth can quickly break up rock, increase drilling speed and reduce drilling costs.
