Dynamic sealing simulation and performance optimization of conical rubber core in rotary blowout preventer

Abstract During the underbalanced pressure drilling, the conical rubber core of the rotary blowout preventer((RBOP) is susceptible to alternating cyclic stress due to the alternating passage of the drill pipe body and its joint, which can easily lead to fatigue cracking and sealing failure. To impro...
