PDC drill bits: New products with super long life,
high efficiency and wide application.
Super long life-as*0
timesascemented
carbide drill bits under the same condition.
High efficiency-Times of lifting the drilling
machine could be reduced sharply, and the average time efficiency
could be increased more than 2 times.
Wide range of application-it could have a
penetration of rock formation with f≤*2,especially
for the rock formation with f=***0.
