Abstract

In snubbing service, the spherical BOP plays a vital role in shut-in well and running and pulling tubing. The shell and rubber core are the crucial components of spherical BOP, taking the three-dimensional software SolidWorks as a platform, these two components 3D model have been established, and the finite element calculation on them have been carried. The calculation results show that under the load of 21MPa, The maximum Von Mises pressure appeared in the junction of ball cover and base, which is 169MPa, the strength of shell structure meets the requirements. The maximum Von Mises pressure of rubber core, which is 348MPa, it also meet the the requirements. The finite-element analysis could provide reference basis for the design of spherical BOP in snubbing service.
