High Manganese Steel Tricone Drill Bit Well Drilling Use 13-5/8"

 

Tricone Drill Bit Description:

 

The tricone drill bit is the most popular drilling bit in the world,it can be widely used for Oil&Gas Drilling,Mining,Water Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit and rubber sealed bit.
1. The C-Center jet can avoid the formation of a ball in the bit, eliminate the fluid area at the bottom of the well, accelerate the upward flow of drilling cuttings and improve ROP.
2. High saturation NBR bearings can reduce sealing pressure and improve sealing reliability.
3. The G-Gauge protection improves the measuring ability and prolongs the service life of the bit.
4. Adding a row of teeth between the rear taper and the outflow to trim the borehole and protect the cone.


Normal IADC Code Of Tricone Drill Bit :

437 Soft Formation TCI Tricone Bits:

The 437 TCI bits are used to drill low compressive strength, very soft formations. TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, results in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.
 

517 Medium Formation TCI Tricone Bits:

The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard formation. The HSN rubber O-ring provides adequate sealing for bearing durability.



637 Hard Formation TCI Tricone Bits:

The 637 bits can be used to drill hard and abrasive formation. Wear-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-shaped inserts are used in all rows to provide cutter durability and long life.



617 Medium-Hard Formation TCI Tricone Bits:

The 617 features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-ring provides adequate sealing for bearing durability.
