Abstract
A blowout preventer (“BOP”) includes a housing comprising a vertical bore extending through the housing and ram cavities intersecting the bore and ram assemblies, each ram assembly movably positionable within a ram cavity. Each ram assembly includes a packer assembly that comprises an upper plate, a lower plate, an elastomeric body positioned between the upper plate and the lower plate and comprising elastomeric material, and a support member comprising an aperture and positioned between the upper plate and the lower plate to provide support to the ram assembly.
Claims18
A method of manufacturing a packer assembly for a ram assembly of a BOP, the method comprising:
- providing a mold with desired dimensions for the packer assembly;
- inserting an upper plate, a lower plate, and support members, each support member comprising an aperture, into the mold such that the support members are positioned between the upper plate and the lower plate and on opposite sides of a pipe profile of the upper plate and the lower plate with respect to each other;
- injecting an elastomeric material into the mold;
- and
- curing the elastomeric material to form the packer assembly such that the aperture is unfilled by the elastomeric material to enable the aperture to receive a portion of the elastomeric material in the aperture when the packer assembly contacts and forms a seal against a pipe in use.
A blowout preventer (“BOP”), comprising:
- a housing comprising a vertical bore extending through the housing and ram cavities intersecting the bore;
- ram assemblies, each ram assembly movably positionable within a ram cavity, each ram assembly comprising a packer assembly comprising:
- an upper plate and a lower plate, each comprising a pipe profile formed therein;
- an elastomeric body positioned between the upper plate and the lower plate and comprising elastomeric material;
- and
- support members positioned on opposite sides of the pipe profile with respect to each other, each support member comprising an aperture that is unfilled by the elastomeric material during manufacturing to enable the aperture to receive a portion of the elastomeric material as the ram assembly moves to a closed position in which the ram assembly forms a seal against a pipe when in use, the support members positioned between the upper plate and the lower plate to provide support to the ram assembly.
