Packer with pivotable anti-extrusion elements
Abstract:
A packer includes a sealing element positioned at least partially around a tubular, the sealing element having an axial end, a gage ring positioned at least partially around the tubular and adjacent to the axial end of the sealing element, and a plurality of petals pivotally coupled to the gage ring, extending at least partially axially therefrom toward the sealing element, and positioned radially outwards of the axial end of the sealing element. The gage ring is movable axially along the tubular, towards the sealing element, such that the gage ring applies an axial force to the sealing element to expand the sealing element radially outwards, and the plurality of petals are configured to pivot radially outwards when the sealing element radially expands.
