Roller Cone applies three sealing types including rubber sealing, composite sealing and metal sealing which better fit to different drilling conditions.
Hard Facing along with carbide inserts blanket the shirt tail and leg providing wear assistance. In order to meet customer different requirement, customized roller cone would be produced to provide optimal drilling solution.
Advantages
1.Realiable Bearing and Sealing Design
2.Enhanced Shirt-tail and Leg Protection
3.High capacity reservoir
4.Cusomized Product

Main structure features of single cone bit:
-With particular structure of the cone,equal worn of the compacts in permanent contact area and alternative contact area of the bit is realized.
-Wear resistance of the cutting structure is enhanced by setting PDC cutters in the permanent contact area of the cone where compacts are most severely worn.
-Optimized hydraulics structure improved the cleaning ability of hydraulic system on cone and bottom hole,and assure higher ROP.
-The bit has excellent gage protection and up reaming abilities by setting active cutting conical spherical gage compacts on head body.

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 and up drill capability.
3.Bearing Structure
High precision journal bearing. Balls 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 watercourse 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.
