Abstract:
A downhole tool has a mandrel with a sealing element disposed thereabout. The sealing element is movable from an unset position to a set position in which the sealing element engages the well. Extrusion limiters are positioned at the ends of the sealing element. The extrusion limiters have first and second layers and the first and second layers are different materials. The second layer may be made up of a plurality of discs. At least one of the discs may be a disc with an irregularly shaped outer peripheral edge and a generally circular inner peripheral edge. A plurality of the discs with the irregularly shaped outer edge may be stacked and may be stacked with a generally circular or ring-shaped segmented disc. The first and second layers are stacked and then molded into a final shape for placement at the ends of the sealing element.
