Tricone Bit
Tricone bits are widely used drilling tools with a distinctive design consisting of three rotating cones. They are capable of effectively drilling through various formations and play a crucial role in the success of drilling operations in diverse industries including oil and gas exploration, water well drilling, mining, and horizontal directional drilling.
Bearings
High-quality bearings are used to support the rotation of the cones. These bearings need to withstand the axial and radial loads generated during drilling while maintaining smooth rotation.
Sealing
Tricone bits have seals to prevent drilling fluids from entering the bearings and damaging them. Proper sealing is crucial to maintain the longevity of the bit and prevent premature failure.
Formation Compatibility
Different Tricone bit designs are available for drilling various types of formations. For example, there are Mill tooth bits optimized for soft formations , TCI bits designed for medium-hard formations, and hard or abrasive formations.
Bit Sizes
Tricone bits come in a range of sizes, from 3 1/2″ to 26″ in diameter. The choice of bit size depends on the borehole diameter required for the specific drilling operation.
Advantages
Tricone bits (IADC117 to IADC847) offer versatility across different formations, providing efficient drilling in a wide range of geological conditions. They are capable of handling variations in hardness and composition that might be encountered while drilling.
Cutting Structure
Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new formula and new techniques of insert bit.
Gauge Structure
The multiple heel position with gauge trimmer on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection.
Bearing Structure
High precision journal bearing with two thrust faces. Ball locked cone. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed.
Seal and Lubrication
The bearing seal is adapting the high quality HNBR O-ring. The best seal compression and the radial seal structure can enhance the seal performance. The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability.
Product Predominance
It can absorb high WOB in the conventional drilling. It is for various formations drilling by matching different teeth shape, teeth density and cutting exposure structure.
