In oil and gas drilling engineering, abrasive formations (such as sandstone, conglomerate, and quartz diorite) have always been the ultimate test for drill bit longevity. Due to the high hardness and strong abrasiveness of these rocks, conventional tri-cone bits often face rapid tooth wear, prematur

Polycrystalline Diamond Compact (PDC) cutters are the core consumables for hard rock drilling in oil drilling, geological exploration, mining, and other industries. Their performance directly determines drilling efficiency, construction costs, and drill bit service life. In high-compression and high

IntroductionPDC drill bits are the most widely used rock-cutting tools for modern water well drilling projects. Compared with traditional roller bits, PDC bits feature faster penetration speed, lower drilling cost, and stable performance in soft to medium-hard formations. However, bit service life a

Tricone bits are core drilling tools for water well projects, and reasonable selection directly determines drilling efficiency, wellbore quality and construction cost. The primary selection principle is to match bit type, tooth structure and sealing form with actual stratum conditions. For soft form

In modern oil drilling, geological exploration, and engineering construction, the drill bit is known as the "pioneering vanguard" of the entire drilling operation. Among the various types of drill bits, the PDC drill bit (Polycrystalline Diamond Compact Drill Bit) has assumed a dominant po

In oil drilling, geological exploration, water well drilling, mining drilling and other engineering projects, tricone bits are one of the most widely used rock-breaking tools. According to their tooth structure, they are mainly divided into TCI Tricone Bits (insert tooth) and Milled Tooth Tricone Bi
