Matrix Body PDC Core Bit
Design for higher ROP in drilling deeper and harder formations, PDC drill bit always drills from ground to bottom directly with less or even a single run, saving large amount of drill time and cost .
Differ from tricone bit, PDC drill bit runs with lower WOB but Higher RPM, so it usually works with downhole motor to pick up rotating speed.
The performance of PDC drill bit depends a lot on PDC cutters, we provide unique solution to specific requirement on varied formations.
It is resistant to erosion with long service life which can greatly improve drilling effeciency and save cost.
1.Drilling in medium to hard formations: The drill bit has medium and short parabolic crowns, knife-wing teeth and medium-high density cloth teeth. It can obtain higher rotary speed in formations with low compressive strength and a small amount of abrasiveness.
2.Proprietary Cutting Teeth: 13mm imported special cutting teeth improves the ability to drill hard interlayer.
3.Strengthened Gauge: The use of high strength material improves the wear resistance of gauge and makes it have a longer life with the drill bits.
