AI Technical Summary
Existing PDC drill bits have a short cutting tooth life in deep hard rock drilling, resulting in low drilling speed, high cost, frequent drill bit replacement, and reduced drilling efficiency.
Design a forward and reverse PDC drill bit, in which the cutting teeth cut rock in both clockwise and counterclockwise directions. The forward and reverse cutting extends the service life of the cutting teeth, and the nozzle assembly cleans the rock cuttings, reducing mud packing. An anti-detachment component enhances the connection stability of the drill bit.
It extends the service life of the cutting gear assembly, reduces the number of drill bit replacements, improves drilling efficiency and speed, reduces economic losses, and lowers manufacturing costs.
