Cone bit with good structural characteristics:
1 with the rolling cone bit sealed bearing, cylindrical roller body rolling groove is placed, , with better performance in use.
(2) In sub-cone bit thrust bearing surfaces respectively antifriction treatment and hardening, hardening anti-drill protection.
3 using can withstand 250 ° C high temperature wear resistance of the new grease.
4 using the differential pressure limit and prevent the drilling fluid into the lubrication system, Improved cone bits oil capsule full rubber, the bearing lubrication system provides a good guarantee.
Cone bit is a bit slow, that cone speed is smaller than the speed of the drill, mainly scraping broken rock, suitable for high speed, high WOB sidetracking of old wells, old wells deeper wells, etc. Eye drilling operations play an important role in the drilling. Cone bit advantages: relatively wide application field, not only for side drilling, and can be used in deep wells, the drilling has demonstrated important advantages.
Tricone rock bit of both the advantages and PDC drill bits, tricone bit more than for both strength and ductility are large formations, but also can be applied to PDC bit difficult to deal with hard interlayer and other complex formation.
