Packers and methods of use

摘要

Expandable packers and methods of using same are described. The expandable packers include an anti-extrusion layer comprising a fibrous layer having a first surface adjacent an outer surface of an inner expandable elastomeric member, and a cable layer adjacent the fibrous layer, the cable layer comprising a plurality of stacked unidirectional layers of cables. The cable layer is adapted to form a barrier substantially devoid of gaps through which the inner elastomer member would otherwise extrude into upon expansion of the inner elastomeric member.
