High Performance TCI 6-1/4 Inch Three Cone Bit For Water Well Drilling
Bearing Structure
High precision journal bearing with two thrust faces.Balla lock the cone.Hardfaced head bearing surfaces.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure resistance of the bearing are improved.
Seal and Lubrication
Premium HNBR O-ring.optimal seal compression and curved seal structure can enhance the seal performance .The pressure compensator system and advanced grease can greatly increase the lubricating rellability.
Product Application
It can receive high WOB in the conventional drilling.It is suitable for various formations by matching cutting structure with different tooth shape,tooth density ans tooth exposure height.
Recommended Drilling Parameters
| IADC | WOB (weight on bit dia) | RPM(R/Min) | Application Formation |
| 116 117 | 0.35-0.8 | 150-80 | Very soft formations with low compressive strength and high drillability.such as clay.mudstone.chalk.etc. |
| 126 127 | 0.35-0.9 | 150-70 | Soft formations with low compressive strength and high drillability,such as mudstone,gypsum salt.soft shale.soft limestone.etc. |
| 136 137 | 0.35-1.0 | 120-60 | Soft to medium soft formations with low compressive strength and high drillability,such as medium soft shale.anhydrite.medium soft limestone,medium soft sandstone.soft formation with harder interbed,etc. |
| 216 217 | 0.4-1.0 | 100-60 | Medium formations with high compressive strength,such as medium soft shale.anhydrite.medium soft limestone.medium soft sandstone.soft formation with harder interbed.etc. |
| 246 247 | 0.4-1.0 | 80-50 | Medium hard formations with high compressive strength.such as abrasive shale.limestone,sandstone.dolomite.anhydrite.marble.etc. |
| 417/437447 | 0.35-0.9 | 150-70 | Very soft formation with low compressive strength and high drillability.such as clay.mudstone.chalk.gypsum.salt.soft shale.soft limestone.etc. |
| 517 527 | 0.35-1.0 | 140-60 | Soft formation with low compressive strength and high drillability.such as mudstone.gypsum.salt.soft shale.soft limestone.etc. |
| 537 547 | 0.45-1.0 | 120-50 | Soft to medium formations with low compressive strength ,such as medium soft shale.medium soft limestone,medium soft sandstone.medium formation with harder and abrasive interbed,etc. |
| 617 627 | 0.45-1.1 | 90-50 | Medium hard formations with high compressive strength.such as hard shale.limestone,sandstone.dolomite.etc. |
| 637 | 0.5-1.2 | 80-40 | Hard formations with high compressive strength.such as sandstone.limestone,dolomite. anhydrite.marble.etc. |
