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.
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.
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.
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.
Detailed Description of the four types TCI Bits(Tungsten Carbide Insert Bit)
2. Elastomer sealed bearing TCI Bit
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°
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.
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.
3. Air Cooling Roller Bearing TCI Bit
The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques.
Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.
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.
4. Non-Sealed Roller Bearing TCI Bit
Dubowitz also recommended that Washington vigorously enforce Iran sanctions, imposing heavy penalties on Tricone bit violators. His full statement is available.
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.
