摘要：
A packer assembly which incorporates a swellable elastomeric packer element and one or more swellable thermoplastic components. The swellable thermoplastic components are support rings that are located at each axial end of the elastomeric element and provide positive mechanical backups for the elastomeric element to limit extrusion of the packer element.
