TCI Tricone Bit 2 7/8 REG PIN Thread Connection Hard Rock Drill Bit for Oil Field and Water Well

Application of Tricone Drill Bits in Oilfield Water Well Drilling:

Tricone drill bits are widely deployed in oilfield water well drilling due to their adaptability

to varying subsurface conditions, cost efficiency, and reliable performance.

Designed for soft to medium-hard formations commonly encountered in aquifers—such as

unconsolidated sands, shales, and limestone—these bits leverage their three rotating cones

to deliver steady penetration rates while maintaining borehole stability.

The hardened steel teeth or tungsten carbide inserts efficiently crush and scrape through

sediment layers, ensuring minimal deviation for precise well alignment. Sealed bearing systemsprevent infiltration of abrasive particles and corrosive fluids, critical in brackish or sandy

environments. Their robust construction reduces tripping frequency, enabling continuous

operation in high-volume water well projects. Additionally, rapid cuttings removal and balancedload distribution minimize torque fluctuations, safeguarding downhole equipment.

Ideal for both shallow and intermediate-depth wells, tricone bits optimize drilling timelines while

balancing operational costs, making them a cornerstone tool for sustainable groundwater resource

development in oilfield regions.

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.
