Detailed Description
Product description

TCI Tri-cone Bit Roller Cone Bit

 

Cutting Structure: The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.

 

Gauge Structure: Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the 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 and suitable for high rotary speed.    2.The advanced metal seal package will improve the reliability and durability of bearing seal

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

 

IADC tricone roller cone classification system

4 character code, first 3 characters are numbers, the last is a letter 

 

1st number is the series. 1 to 3 represent a milled tooth tri cones, 4 – 8 represent TCI tri cones.  The higher the series number  the harder more abrasive the rock formation is. 

2nd number is the relative degree of hardness within a series. The number ranges from 1 – 4, the higher the  number  the  harder the formation 

 

3rd number represents bearing design and gauge protection. 

  • Open bearing 
  • Roller bearing air cooled 
  • Open bearing gauge protected 
  • Sealed roller bearing 
  • Sealed roller bearing gauge protected 
  • Sealed friction bearing 
  • Sealed friction bearing gauge protected 

4th character is a letter and describes optional features. There are 16 alphabetic characters each representing the tricones 

most significant feature

 

rock drill bits application instructions 

 

1 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 befor 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.make up the 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

 

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
