Abstract:
A sealing system for sealing with a generally interior cylindrical surface of a tubular or a tool, the sealing system comprising:an axially extending annular packer element including a metal base, and a first elastomeric seal body spaced axially from a second seal body, the first seal body having an outer diameter for initially sealing with the cylindrical surface, the second seal body having an elasticity lower than the first seal body, the annular packer element having a reduced diameter initial position and an expanded diameter sealing position; a wedge ring radially inward of the packer element and having a substantially conical outer surface configured to radially expand the packer element to the expanded sealing position upon axial movement of the packer element relative to the wedge ring; and a positioner for moving one of the packer element and the wedge ring relative to the other of the packer element and the wedge ring, the positioner initially sealing the first elastomeric seal body with the cylindrical surface.
