 rock bits 

 

 

 

The  structure characteristics of the rock bit:

1. The cone bit rolling bearing sealing structure, cylindrical roller in a two-foot depression cone body, increased the shaft neck size, has a better performance in use. 

2. The cone bit bearing pair of surface by grinding processing respectively and the hardening treatment, reduce the friction, bit protect bit hardening resistance.

3. Adopt to 250 ° C high temperature resistance, wear resistance of the new type of grease.

4. Use may limit the differential pressure and prevent drilling fluid into the lubrication system of the whole rubber oil storage pouch, guarantee for the good lubrication bearing system.

Cone bit is a kind of slow bit, that is, the speed of the cone to smaller than the speed of the bit, mainly by scraping and broken rock, adapted to the old well under the high speed, high wob window sidetracking and old well deepening of slimhole drilling operation, play an important role in drilling.Rock bit's advantage lies in: application field is wide, not only suitable for lateral drilling construction, and can be used in deep well, show significant advantage in drilling.    

    
Work torque than PDC bit under the condition of the same weight on bit and formation is lower and small size can be reduced by drill bilge buckle problem, avoid downhole accidents.Cone bit has both the advantages of tricone bit and PDC bit, and made up for the inadequacy of the two respectively, more than three cone bit is suitable for the strength and plasticity are big formation at the same time, also can apply to PDC bit difficult to deal with hard interlayer and other complex formation.
