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 Hebei Province, 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 |
