One cone bit's features
1. Cutting structure
In response to the characteristics that inserts in different areas on the cone have different cutting
actions, conical inserts are placed in permanent contact area and wedge inserts are placed in
alternative contact area so that the drilling efficiency is greatly improved. Wear resistance of cutting
structure is enhanced by setting diamond inserts in the permanent contact area of the cone where
inserts are severely worn. Tungsten carbide inserts are placed on cone top face to protect cone
body from abrasive erosion.
2. Gauge Structure
With active cutting gauge protection inserts on bit body, the bit has good gauge protection inserts
on bit body, the bit has good gauge protection and up drill capability.
3. Bearing Structure
High precision journal bearing, Ball lock the cone. Hardface heard bearing surface. Cone bearing
inlaid with friction reducing alloy. Abrasion resistance and seizure resistance of the bearing are improved. Compared
with three cone bit, the leg bearing is bigger, so it can receive higher WOB and high reliability.
4. Hydraulic Design
Small angled water course design increased the shirttail thickness and can effectively prevent the
watercourse erosion. Optirnized hydraulics structure improves the clearing capability and increases ROP.
5. Product Application
It is suitable for sidetracking, deep well drilling and old well repairing.
