1. Enhanced Bearing Durability
Equipped with high-precision journal bearings, dual thrust faces, and a silver-plated friction-reducing alloy, providing excellent wear resistance and stability at high rotary speeds.
2. Advanced Metal Sealing System
Features a metal-to-metal seal structure with dual metal seals and elastic energizers for reliable sealing under extreme drilling conditions. This ensures longer bearing life and higher operational reliability.
3. Superior Lubrication System
Integrated pressure compensator and high-performance grease significantly improve lubrication efficiency and protect internal components from wear and heat.
4. Optimized Cutting Structure
Steel tooth bits are reinforced with high-density tungsten carbide hardfacing for extended wear life. Insert bits use newly formulated tungsten carbide inserts to improve impact and compressive resistance.
5. Comprehensive Gauge Protection
Multiple gauge protections including gauge inserts, heel trimmers, and shirttail hardfacing help maintain borehole diameter and improve the durability of the cutting structure.
6. High Speed & High Load Capability
The combination of metal seal, precision bearing, and wear-resistant cutting structure enables the SJ Series bit to perform efficiently in high-speed and high-load drilling environments.
7. Extended Bit Life
All structural enhancements contribute to longer service life, reduced tripping times, and improved drilling efficiency, reducing overall drilling costs.
1.Oil and Gas Drilling
Ideal for medium to hard formations in onshore and offshore oil and gas exploration and production.
2. Geothermal Drilling
Performs reliably under high-temperature, high-pressure geothermal conditions due to its robust metal seal and bearing design.
3.Water Well Drilling
Suitable for deep and complex water well drilling, providing durability and long service life.
4. Mining and Mineral Exploration
Used in drilling blast holes and exploration holes in hard rock formations.
5. Construction and Infrastructure Projects
Applicable in drilling foundation piles, tunnels, and other geotechnical engineering projects requiring rock penetration.
6. Horizontal Directional Drilling (HDD)
Can be used for trenchless drilling applications in tough geological conditions.
