Product Description

TCI Tricone Bit/Roller Cone Bit/Rock Bit for Drilling

 

Tricone bit is mainly used in oil well,water well, and geothermal well drilling engineering.Our well drilling bit is designed and manufactured according to the standard of API 7-1. Its features as long life, high drilling efficiency and low operation cost. At present, more than 20 types drilling bit with sizes ranging from 3" to 26" have been developed by our team, which can be applied to different formations from soft to very hard. There are two main bearings which are O-Ring sealed and Metal Sealed,it can meet clients difference requirements with different drilling technologies such as conventional drilling and directional drilling.

Description of tricone bit

(1) Cutting Structure: The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.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 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 bearing with two thrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.

(4)Seal and Lubrication: The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal are relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal.
The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
