Introduction

The TCI tricone bit is a key tool in oil drilling. As it operates, its cutting teeth make contact with the well bottom alternately, which produces low rock-breaking torque. The small contact area creates high specific pressure, allowing the bit to easily penetrate the formation. Thanks to the long total working edge, wear is comparatively low. This tricone bit performs well in a wide variety of formations, from soft to hard.

Features

Bearing StructureAdopts high-precision journal bearings with dual thrust faces. The cone is securely locked by ball bearings. The head bearing surface is hardfaced for enhanced durability. The cone bearing is inlaid with friction-reducing alloy and silver-plated, greatly improving abrasion and seizure resistance, making it ideal for high-speed drilling.
CutterEquipped with high-grade carbide teeth that deliver superior breakage and abrasion resistance, effectively extending the service life of the cutting structure.
Gauge ProtectionExtra tungsten carbide inserts are installed on the gauge to minimize wear in highly abrasive formations. This design protects the gauge, improves bit stability, and prolongs service life.
NozzleSturdy and high-performance nozzles ensure excellent flow capacity and optimized fluid distribution to the cones.

Technology

Seal and LubricationThe bearing assembly is fitted with high-grade HNBR O-rings. Featuring optimized sealing compression and a radial sealing structure, it delivers greatly improved sealing performance. Equipped with a pressure compensation system and premium drilling grease, it effectively stabilizes pressure differences and ensures outstanding lubrication reliability.
Six-point Gauge StabilityThis unique structure achieves near six-point contact with the borehole wall, providing exceptional drilling stability. It effectively shields the cutting structure from lateral shocks and damage.
Motor HardfacingHigh-density tungsten carbide hardfacing is applied to the shirttail area and extended to the leading edge of the bit leg. This offers reinforced protection for high-speed, directional, and highly abrasive drilling conditions.

Application

Soft to hard formations with several hard inter-bed,such as clay/chalk/ compressive mudstone/hard gysum/salt/shale/limestone/dolomite.etc
