The metal-sealed insert tricone bit features a rigid seal structure that ensures stable high-speed drilling, making it a perfect choice for directional and horizontal wells. When used with downhole motors, this bit delivers superior performance. Compared to conventional rubber-sealed bits, our metal-sealed tricone bits offer a 35% increase in average lifespan (pure drilling time) under the same drilling parameters.
Key features include:
- High-Strength Alloy Teeth: Optimized design with carefully arranged tooth rows, tooth count, exposure height, and shape maximizes cutting efficiency.
- Rigid Sealing Technology: A precision-engineered rigid seal with a coating on the seal contact surfaces enhances durability and extends bit life.
- Bearing Protection: Sliding bearing surfaces are coated with a wear-resistant alloy, and the roller-bearing interior is silver-plated for increased load capacity and anti-seizing properties.
- Extended Gauge Protection: The bit incorporates advanced materials for gauge protection, featuring an extended full gauge structure that reduces friction with the wellbore, protecting the gauge and ensuring good stability.
- New Oil Reservoir Design: Improves bearing lubrication and reduces wear.
- High-Speed Adaptability: Ball lock mechanism stabilizes the bit at high speeds.
Our metal-sealed tricone bits are API-compliant, offering a high-value alternative to more expensive American and European brands while meeting industry standards. Located in the Southwest, we are a key supplier of drilling equipment and oilfield accessories worldwide.
Recommended Drilling Parameters (For Reference):
| Formation Type | IADC Code | Weight on Bit (KN) | Rotation Speed (RPM) |
|---|---|---|---|
| Very soft formations with low compressive strength, such as soft shale, clay, loose sandstone, and salt. | 437X | 30-90 | 180-60 |
| Soft formations with low compressive strength and high drillability, including shale, clay, sandstone, and soft limestone. | 517X | 35-105 | 180-60 |
| Medium-soft formations, such as shale, sandstone, hard gypsum, and claystone with hard inclusions. | 537X | 35-105 | 180-40 |
| Medium-hard formations with high compressive strength, like hard shale, limestone, sandstone, and dolomite. | 617X | 40-105 | 160-40 |
| Hard formations with high compressive strength and abrasive properties, including limestone, dolomite, sandstone, and chert. | 637X | 50-105 | 160-40 |
