Tricone Roller Cone Drill Bit High Performance Water Well Drilling Bit 7 7/8

Product Specification

Oil and Gas Exploration:
Roller cone bits are extensively used in drilling petroleum and natural gas wells. They excel in crushing and fracturing diverse rock types—from soft shale and sandstone to hard limestone and dolomite—enabling efficient wellbore creation for extraction and production.

Mining and Mineral Exploration:
These bits facilitate core sampling and blast hole drilling in mining operations. They are ideal for excavating mineral deposits, coal seams, and ore bodies, providing precise cutting performance in both surface and underground mining environments.

Geotechnical and Water Well Drilling:
In geotechnical engineering and hydrogeology, roller cone bits help construct water wells, monitoring wells, and foundation boreholes. Their ability to handle unconsolidated sediments, clay, and mixed rock layers ensures reliable performance in aquifer exploration and civil engineering projects.

Tricone roller cone drill bit  are highly effective in a wide range of geological conditions, from soft sediments to hard and abrasive rock layers. The design allows for efficient penetration, cuttings removal, and heat dissipation, enhancing drilling speed and durability. Roller cone bits are commonly paired with tri-cone configurations—three cones arranged symmetrically—to ensure stability, balance, and uniform wear during operation.

Efficient Cuttings Removal:
Nozzles and flow channels facilitate optimized drilling fluid circulation, clearing debris rapidly and preventing balling—critical for maintaining penetration rates.

Adaptability to Formations:
excels in diverse geological settings, from soft sediments to fractured or interbedded rock, thanks to its crushing, chipping, and shearing action.
Cost-Effectiveness:

Combines robust performance with relatively low operational costs, reducing downtime and frequent bit changes in long-interval drilling.
These features collectively enhance drilling precision, efficiency, and reliability across oil and gas, mining, and geotechnical applications.
Durability and Heat Resistance:
Constructed from high-strength alloys and composites, the bit withstands extreme pressure, torque, and temperatures while minimizing failure risks.

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.
