Hybird PDC bits are compounded by the PDC fixed cutting and the roller free cutting structure.
Description
Hybird PDC bits is matched with cone optimization, and the drill bit has strong adaptability and high rock-breaking efficiency in hard-drilling strata.
The Hybird PDC bits utilizes the cutting advantages of PDCs soft formations and the rock breaking strength and stability of roller cones
in hard or intercalated formations, with the potential to maintain a higher total rate of penetration (ROP) than an older cone or PDC single bit over a larger range of footage.
The balance analysis and optimization of the composite cutting structure balance the working stability of the drill bit with the adaptability of the formation and improves the service life.
Computational fluid dynamics (CFD) optimization analysis of bit watercourse and nozzle to improve flow field distribution and cleaning cooling effect.
