Swellable packer with composite material end rings

摘要

A swellable packer with composite material end rings. A packer assembly includes at least one generally tubular seal element extending longitudinally between opposite ends thereof. At least one end ring is positioned proximate one of the seal element opposite ends. The end ring includes a nonmetal material. A method of constructing a packer assembly includes the steps of: chemically bonding at least one end ring to a base pipe; providing at least one generally tubular seal element which extends longitudinally between opposite ends thereof; and restricting longitudinal displacement of the seal element relative to the base pipe utilizing the end ring positioned at one of its opposite ends.
