Mechanical Prerequisites for Proper Selection of the Cone Semivertex Angle of the Packing Unit on Annular BOPs |

| Abstract: | According to the sealing function and the required service behaviour of the annular blowout preventer, the author establishes the functional relation between the enclasping force q and the cone semivertex angle θ of the rubber packing unit, determines the threshhold values of q and θ, and presents the mechanical prerequisites for selecting the rational value of θ in order to ensure optimum operational performance of the blowout preventer. |
