2021 new rotary digging cone palm for hard stratum

  1
The cone bit has a rolling sealed bearing structure, and the cylindrical rolling body is placed in the groove of the cone body, which increases the journal size and has better performance in use
  2
Wear reduction treatment and hardening treatment shall be carried out on the thrust bearing pair surface of cone bit to reduce the friction of bit and protect the anti hardening ability of bit
  3
Adopt 250 DEG resistant; C new grease with high temperature and wear resistance

  4
The full rubber oil reservoir which can limit the differential pressure and prevent the drilling fluid from entering the lubrication system provides good lubrication protection for the bearing system
  Cone bit is a kind of deceleration bit, that is, the rotation speed of cone is smaller than that of bit
It mainly scrapes and breaks rock, which is suitable for opening windows in old wells under high rotation speed and high WOB
Slim hole drilling operations such as sidetracking and old well deepening play an important role in drilling
The advantage of cone bit is that it has a wide range of applications
It is not only suitable for side drilling, but also can be used in medium and deep wells, showing important advantages in drilling
