The hardness of diamond is 10 times that of steel, twice that of tungsten carbide, the wear resistance is 10 times that of cemented carbide, and the compressive strength of diamond is 20 times that of granite. The use of diamonds has become an irreversible trend in oilfield drilling operations.
The quality of today's cutting teeth greatly improves the erosion and impact resistance of the drill bit. Engineers also optimized the interface between tungsten carbide substrates and synthetic diamonds to improve the toughness of the cutting teeth. Innovations in the layered diamond process have also been used to improve the abrasion and thermal stability of the product. PDC products have also achieved significant breakthroughs in tooth design techniques and gear teeth. Today, PDC products can be used in harder, more abrasive and lithologic formations. Currently, PDC bits are increasingly crowding the market for roller cone bits in many drilling applications.
