A rotary BOP is a well control device usually applied in underbalanced drilling wells. The rotary blowout preventer is made up of the body, the clamping cylinder assembly, the rotating assembly and the drilling rod driver assembly. The well control device has a packing element or double packing elements.

Features
  • The BOP bearings adopt dynamically forced lubrication.
  • The dynamic seal part uses a structure of packing box which can be replaced quickly.
  • The BOP’s cooling system cools the upper dynamic seal in a sustainable manner.
