Petroleum exploration has been developed to deep formations gradually, in deep formations (compact plastic mudstone, lava and granite etc.,), low ROP restrict the economic of development in deep well or super-deep well. Failure types, such as tooth break, tooth wear, cone tip wear and bit diameter shrink etc., usually appear when conventional cone bits drill in hard formations. So we have developed HF series bit for hard formations through analyze and research these failure types deeply and make use of advanced computer 3D simulation technology and lots of platform experiments.

Result in site shows HF series bit has the advantages of long service life, high reliability, fast ROP and strong gage protection ability etc.. HF series bit is the ideal choice for drilling in hard formations and strong abrasive formations effectively and safely.

The size range of HF series bit is 7 7/8- 12 1/4 inch and its IADC code is 537-737.

Long working life and high reliabilty

Head bearing of HF series bit is adopted advanced automatic welding technology with wear-resistant alloy on surface hardfaced and cone bearing surface is plated by using third-generation high-performance composite solid lubricating materials to increase bearing's capacity.Composite solid lubricating material and new type of grease are applied to improve bearing's working environment.The bearing can receive higher WOB under using those bearing technology.

Cutter crest enhancement

Wear between cones of HF series bit is prolong service life by utilizing top inserts enhancing technique.
