Tricone Roller cone drill bits deliver exceptional performance in challenging
drilling operations with their robust multi-cone design. Engineered for superior
durability, these bits utilize hardened teeth or tungsten carbide inserts to withstand
abrasive formations and high-impact environments.
Their optimized cone geometry ensures efficient rock fragmentation while maintainingdirectional stability, significantly improving penetration rates.
The advanced bearing systems and pressure-balanced lubrication extend service life,
reducing downtime for bit replacement. Compatible with various formations from soft
to ultra-hard strata, roller cone bits offer versatile adaptability across oil, gas, and
geothermal applications. Enhanced hydraulic designs improve cuttings removal andcooling efficiency, while their cost-effective performance minimizes overall drilling
expenses per foot.

Notes for the use of roller cone bits:
1 .Before the drill bit is down, it is necessary to confirm that the bottom of the well is clean, free of grit, and no metal falling.
2. Check if the thread connection screw of the roller cone bit is intact and the nozzle is installed properly.
3. Run in hole needs to be stable, avoid stress and prevent drilling.
4. The last joint needs a large displacement to start the rotary table and keep reaming to bottom of the well., fully wash the well to prevent the debris from clogging the nozzle.
5. The shape of the bottom hole should be lightly pressed and slowly turned into contact with the bottom of the well, smalldrilling pressure, low speed, large displacement, small torque, and the speed is 40~60 rev / min, at least 30 minutes.
6. Determine the weight on bit and speed in combination with the actual conditions of the formation.
7. During drilling ahead, the operation should be smooth, drill feeding should be uniform, it is strictly forbidden to lift and release the drill sharply,drill string not well braked and drill string free fall.
8. If it is found that the drill bit stops making progress, the pump pressure increases and decreases obviously, the rate of penetration is suddenly decreased, and the torque is increased, lift the drill to check without delay.
