1, API quality tricone bits
1) Cutting Structure
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
2) Gauge Structure
Multiple gauge protection with gauge trimmers on the 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.
3) Bearing Structure
High precision roller bearing with two thrust faces. Ball lock the cone. Thrust faces hardface with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
4) Seal and Lubrication
Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
5) Product Application
It is suitable for various formations, and achieves high RPM under low to medium WOB application
Low compressive strength; high drillability of soft formation; such as shale; clay; sandstone; soft limestone; etc
Large diameter of partial top form in row tooth, wedge discharge teeth
3, Some IADC code for reference:
Soft Formation TCI Tricone Bits
The 427 tci bits are used to drill low compressive strength, very soft formations . TCI bits maximize the use of bothconical and chisel tungsten carbide inserts of large diameters and high projection. This cutting sstructure 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 517features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This desing 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.
Hard Formation TCI Tricone Bits
The 637bits can be used to drill hard and abrasive formations . Wearresistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of bemisphericalshaped inserts are used in all rows to provide cutter durability and long life.
Medium-Hard Formation TCI Tricone Bits
The 617features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fast drilling rate and added sutti8ng structure durability in medium to medium hard formations . The HSN rubber o-ring he 617features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fast drilling rate and added sutti8ng structure durability in medium to medium hard formations.
Steel tooth bits series
Soft Formation Tooth Bits
The 114-117 bits are used to drill low compressive strength, soft formations . Long projection tooth lengths are used on high offset cones to provide thegreatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear. Onthe softest bit ty0pes this hard facing completely covers the bit teeth.
Medium-Hard Formation Tooth Bits
The 127bits are used to drill high-compressive strength, medium hard formations . Short projection teeth with reduced crest length are used in this series of bit designs . Durable hard facing is applied to reduce tooth wear
