Tricone Bits

Cutting Structure

The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.

Tricone Bits Gauge Structure

Multiple gauge protection with gauge trimmers on the heel and gsuge inserts on the gauge suifame of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capacity and bearing life.

Tricone Bits Bearing Structure

High precision journal bearing with two thrust faces,balls lovk the cone .Hardfaced Head bearing suifame.
Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure of the bearing are improved,and suitable for high rotary speed.

Seal and Lubrication

The advanced metal seal package consists of two metal seals and two elastic energizers.Compressed energizers ensure good contact being kept on two sealing suifaces of metal rings by elastic force ,and achieves the bearing seal .When drilling,metal seals 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 reliabiliry.

Tricone Bits Application

It is suitable for downhole motor and high speed applications.

Recommended Drilling Parameters

IADC	WOB(kN/mm)(bit dia)	RPM(r/min)	Applicable Formations
437 447	0.35--0.9	240--70	Very soft with low compressive strength and high drillability,such as shale,clav,chalk,mudstone,gypsum,sandstone,soft limestone
517 527	0.35--1.0	220--60	Soft with of low compressive and high drillability,such as mudstone .gypsum,salt ,soft shale ,soft limestone.etc.
537 547	0.45--1.0	220--50	soft to medium with low compressive strength ,such as medium soft shale,medium soft limestone,medium soft sandstone and medium formation with harder and abrasiver interbeds .etc.
617 627	0.45--1.1	200--50	Medium hard with high compressive strength such as limestone hard shale ,sandstone and dolomite,etc.
637	0.5--1.1	180--40	Hard fomation with high compressive strength ,such as limestone,dolomite,sandstone,hard gypsum,and marble .etc.
