Roller Cone Bit for Oilfield and Water Well Drilling
The roller cone bit is a versatile and robust drilling tool extensively used in oilfield exploration and water well construction. Its design integrates durability, adaptability, and high-performance cutting mechanisms to address the challenges of varied subsurface formations.
Multi-Cone Cutting Structure:
Features three rotating cones equipped with hardened steel teeth or tungsten carbide inserts (TCI).
Steel teeth excel in soft to medium formations (e.g., clay, shale), while TCI bits penetrate hard, abrasive layers (e.g., sandstone, granite).
Bearing and Seal Technology:
Utilizes sealed roller or journal bearings with advanced lubrication systems to withstand high loads, temperatures, and pressures in deep oilfields or water well environments.
Formation Adaptability:
Engineered to handle diverse geology, from unconsolidated sediments in water wells to hard, interbedded rock in oilfields.
Applications:
Oilfield Drilling:
Used for drilling production wells, exploration boreholes, and directional drilling in hydrocarbon reservoirs.
Provides reliable performance in demanding conditions, including high-pressure and high-temperature (HPHT) environments.
Water Well Construction:
Ideal for drilling water extraction wells, irrigation wells, and monitoring wells in aquifers.
Efficiently penetrates soft sediments, limestone, and sandstone layers while maintaining cost-effectiveness.
Advantages:
High Penetration Rates: Accelerates drilling progress in both soft and hard formations.
Durability: Resists wear and abrasion, reducing downtime and replacement frequency.
Cost Efficiency: Balances performance and operational costs for long-interval drilling projects.
This specialized roller cone bit combines mechanical resilience with precision engineering, making it an indispensable tool for energy and water resource development worldwide.

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.
