2. Elastomer sealed bearing TCI tricone bit

Cutting Structure

   The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit.The Tricone bit field is composed of a shallow sequence of sediments of fluvial origin, in which sandstone channels contain heavy oil with gravity ranging from 11 to 13°

Gauge Structure

    Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.

Sealed Bearing Structure

    1.Abrasion resistance and seizure resistance of the bearing are improved.
    2.Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance.

Main Type Available

 Size: 5 7/8",6",6 1/2",7 1/2",7 7/8",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",14 3/4",17 1/2", etc.
 IADC Code:4-- Series, 5-- Series, 6-- Series,etc.

3. Air Cooling Roller Bearing TCI tricone bit

Cutting Structure

    The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques.

Gauge Structure

    Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.

Bearing Structure

    Air cooling roller bearing package. Balls lock the conewhich reduces the probability of cone-dropping to minimum.The HH Tricone bit Series reduces sound to a maximum of 60 decibels at the location limit, compared to conventional rigs where sound averages up to 120 decibels.

Main Type Available

 Size: 8 1/2",9 1/2",9 5/8",9 7/8",10 5/8",12 1/4", etc.
 IADC Code:5-- Series,6-- Series,7-- Series

4. Non-Sealed Roller Bearing TCI tricone bit

Cutting Structure

    Dubowitz also recommended that Washington vigorously enforce Iran sanctions, imposing heavy penalties on Tricone bit violators. His full statement is available.

Bearing Structure

    Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone Cdropping to minimum.

Main Type Available

  The president is issuing Tricone bit edicts, Congressional representatives are falling over themselves vying for camera time to get their comments out there, and everyone is demanding answers that will not exist until a thorough drill pipe investigation by experienced oilfield professionals has been conducted

 

2. Tricone drill bit  application instructions 

 1 Tricone bit selection

1.Please reading lithology description and bit records of adjacent wells carefully,and analyzing formation 

characteristics.

2.Selecting appropriate type in accordance with lithology.

 

2 Preparation before drilling 

1.Inspect previous bit for body damage, lost cutters or inserts etc. Make sure there are no any junk on 

buttom hole, and clean the bottom hole if necessary.

2.Bit must be handled with care in order not no damage cutters and hard substances.

3.Check if there is any damage on bit cuttes and if there any foreign matter inside the bit.

4.Check if installing nozzle is meet requirements, and replace nozzles if necessary.

3 Marking up the  Tricone bit

1.Clean bit threads and apply grease on threads.

2.Fit the breaker to the bit, lower the drill string onto the pin and engage the threads.

3.Locate the bit and breaker in the rotary bushing, and make-up the bit to be recommended torque.

4 Tripping in tricone bit

1.Remove the breaker and carefully lower the bit through the wellhead device in order not to damage it.

2.Shrinkage,shoulder,dogleg and key seat of borehole should be cautious when bit through blank hole.

3.Start pump and cycle drilling fluid to wash buttom hole when drill to a point about 30 meters to bottom of the 

hole, and rotate drill string at the low speed not more than 60rpm.

4.Approach the bottom approximately half meter. Circulate for 5 to 10 minutes with full flow.

 

5 Reaming 

1.Reaming long sections of undergauge hole is not recommended.

2.If reaming operation is necessary, it is strongly recommended that the reaming operation should be done 

with maximum flow rate circulation,specific weight on bit not exceed 90N/mm (diameter),rotary speed not 

exceed 60 rpm where stuck was encountered when tripping in.

6 Bit break-in

1.Overusing display instruments when bit approch bottomhole. If the WOB and torque increase,that shows 

bit have attived at bottomhole.Use not more than 90N/mm,weight on =bit and 40to 60rpm to establish the bottomhole pattern at least half meter.

2.Bit break-in is finished and should be adjusted RPM to obtain optimal drilling parameter combination.

3.Drilling parameters adjustment should be selected within the limits of the recommended parameters refer 

to recommended drilling parameters optimization method
