Tungsten carbide grinding teeth, roller bit, roller bit, bit for
water and hot oil drilling
Through the special structure of the cone, the permanent contact
area and the alternating contact area of the drill bit have equal
By setting the PDC tool in the permanent contact area of the cone,
the wear resistance of the cutting structure is improved. The
permanent contact area of the cone is where the fastener wears the
The optimized hydraulic structure improves the cleaning ability of
the wellbore and bottom hole hydraulic system, ensuring a higher
mechanical drilling speed.
By arranging an active cutting tapered ball gauge pressure block on
the main body of the drill bit, the drill bit has good protection
performance and the hole reaming ability is improved.
1. Cutting structure:
Using new formulas and new technologies, the durability of
high-quality carbide blades has been improved. The steel teeth
adopt high-quality tungsten carbide surfacing welding on the tooth
surface to improve the wear resistance of the teeth by a small
2. Gauge structure:
Multi-gauge protection, a gauge dresser at the rear, gauge inserts
on the cone measuring surface, tungsten carbide inserts and
surfacing on the tip of the palm, which increase gauge retention
and bearing life.
3. Bearing structure:
High-precision bearing with two thrust surfaces. The ball locks the
cone. The hard surface hears the bearing surface. The tapered
bearing is inlaid with anti-friction alloy and then plated with
silver. Improve the wear resistance and seizure resistance of the
bearing, suitable for high speed.
4. Sealing and lubrication:
The advanced metal sealing package consists of two metal seats and
two elastic energizers. The compression energizer keeps the two
sealing surfaces of the metal ring in good contact through elastic
force to achieve bearing sealing. In drilling, the metal seal is
relatively dynamic, while the energizer is static. This will
improve the reliability and durability of the bearing seal.
Pressure compensation system and advanced grease can greatly
improve lubrication reliability.

Tri-cone bit is a decelerating bit. It is based on the fact that
the speed of the cone is less than the speed of the bit. It is
suitable for sidetracking of old wells and deepening of small
boreholes under high speed and high drilling pressure.
