Design features of this bit
1) metal face sealed journal bearing
Hj series bit uses journal bearing and metal face seal; It can
perform consistently in high speed drilling application.
2) special gage protection on cone
A row of trimmers is added between heel row and gage row compacts.
As a result, not only cone shell is protected, but also the
borehole wall is properly trimmed.
3) head od reinforcement
Head od are designed with carbide inserts to protect the shirttail
and seal to effectively improve the bit's ability to prevent
4) hardfacing on shirttail
This feature can provide better protection for seal and bearing to
extend the bit's service life.
5) center nozzle
Center nozzle can avoid bit balling, eliminate fluid stagnant area
at bottom hole, increase rising velocity of drilling cuttings, and
improve rop, which is suitable for drilling formations from soft to
middle soft with low compressive strength and high drillability.
Recommended operating parameters
Wob 90 ~ 280(kn)
Ideal wob range 150~220(kn)
Rotary speed 80 ~ 300 (rpm)
Ideal rotary speed range 110~250(rpm)
The above parameters are only for reference. Optimized parameters
are determined by drilling process and lithology of formations on
Very soft with low compressive strength and high drillability, such
as shale, clay, sandstone and conglomerate, etc.
