Anti-whirl Technology | The advanced simulation technology, enables the bit more stable in drilling, it can drill interbred formations without serious broken and wear as conventional PDC design |
Advantage | Fast drill speed and more safety |
Features | 1.Which is a matrix body PDC bit using are-type double rows spiral desing with 5 blades,long parabolic crown structure,the rational allocation of different functions of the small size of the cutters. 2. Heavy cutter layout and high wear wide gauge design,effectively improve the PDC bit impact resistant and abrasive. 3.While using a dynamic flow simulation technology to optimize the hydraulic design of the PDC bit. |
