Cheap Price Tricone Drilling Bits Hard Rock Drill Bit Petroleum Exploration Tricone Button Bit

Petroleum Exploration Roller Cone Bits Specifically engineered for hydrocarbon drilling,

petroleum exploration roller cone bits are tri-cone cutting systems optimized for drilling

through stratified sedimentary formations typical in oilfields. Their hardened steel or

tungsten-carbide-insert teeth deliver effective shearing action across diverse lithologies

including shale, sandstone, limestone, and marl.

These bits achieve high performance in both vertical and directional wellbores, with

asymmetric cone designs enhancing stability in deviated drilling. Jet nozzle configurations

facilitate efficient mud circulation for cuttings removal while preventing bit balling in

clay-rich zones.

Models are graded by IADC classifications for precise formation matching:

soft-formation variants prioritize aggressive tooth profiles for rapid ROP (Rate of Penetration),while ultra-premium inserts combat wear in quartz-bearing reservoirs.

Their mechanical durability reduces trip frequency during deep exploration wells, crucially lowering

drilling costs per foot in complex subsurface environments.

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.
