Seal Bearing Trenchless Steel Tooth Roller Cones Bits/Rotary Tricone Bits Well Drilling Tools
Introduction
The selection of performance sealing rings for bearing sealing, optimal sealing compression, and arc-shaped sealing structure effectively improve the performance of bearing sealing. Using high-performance drill bit specific lubricating grease. Capable of withstanding high drilling pressure at regular rotational speeds, combined with cutting structures with different tooth shapes and cutting heights, it is suitable for drilling in various formations.
| Suitable Formation |
| IADC CODE | Rock Formation | WOB KN/mm | PRM(r/min) |
| 115 | Extremely soft formations with low compressive strength and high drillability, such as clay, mudstone, chalk. | 0.3~0.75 | 180~60 |
| 117 | Extremely soft formations with low compressive strength and high drillability, such as clay, mudstone, chalk. | 0.35~0.8 | 150~80 |
| 127 | Soft strata with low compressive strength and high drilla-bility, such as mudstone, gypsum, salt rock, soft shale, and soft limestone. | 0.35~0.9 | 150~70 |
| 217 | Soft to medium strata with low compressivestrength, such as medium soft shale, medium softlimestone, medium soft sandstone, and soft strata with hard intercalation. | 0.4~1.0 | 100~60 |
Features
1. High strength, high elasticity, high temperature resistance, high wear resistance.
2. High precision metal seal.
3. Lock the balls to adapt to high speed.
4. Using high-strength and high-toughness carbide teeth,
Used in
Tri-cone bit is a decelerating bit. It is based on the fact that the speed of the cone is less than the speed of the bit. It is suitable for sidetracking of old wells and deepening of small boreholes under high speed and high drilling pressure.
