SANROCK Oil Well Tricone Bit Wear Resistant Roller Drill Bits TCI Tricone

Product Specification

Tricone cone drill bit is a type of roller cone bit featuring three conical-shaped, rotating cutting structures (cones) mounted on precision bearings. Designed for rotary drilling applications, it efficiently penetrates subsurface formations through a combination of crushing, fracturing, and shearing actions.
Utilizes sealed roller or journal bearings with lubrication to withstand high axial/radial loads, extending operational life in extreme downhole conditions.
Efficient Debris Removal:
Nozzles and fluid channels enable optimized drilling mud circulation, preventing cuttings accumulation (e.g., balling) and maintaining clean cutting surfaces.
Versatile Formation Compatibility:
Excels in diverse geology, from unconsolidated sediments to interbedded rock layers, by adjusting cone geometry, tooth profile, and journal angles.
Applications:
Oil & Gas Drilling: Primary choice for drilling boreholes in hydrocarbon exploration and production.
Mining & Quarrying: Used for blast hole drilling and mineral exploration.
Water Wells & Geotechnical Projects: Employed in constructing water extraction wells and foundational boreholes.

Advantages:
High penetration rates across variable formations.
Reduced downtime due to robust construction and heat resistance.
Cost-effective performance in medium to hard rock environments.
The tri-cone bit remains a cornerstone technology in drilling industries, combining mechanical reliability with tailored design for efficient subsurface excavation.

Products Description

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.
