8 1/2" Single cone bit TCI bits used in well drilling
(1) Hydraulic Design:
Small angled water course design increased the shirttail thickness and can effectively
prevent the watercourse erosion. Optimized hydraulics structure improves the clearing
capability and increases ROP.
(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)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.
Product Application:
It is suitable for sidetracking, deep well drilling and old well repairing.
