20130147121 | Backup System for Packer Sealing Element - Backup rings are disposed on opposed sides of a sealing element. The backup rings are initially bow shaped in the run in position. Opposed ends of the bow shape are brought together to extend the extrusion barriers and compress the sealing element. The relative axial movement that brings the opposed ends of the bow shape together results in radially extending the bow shape. The bow shape is reformed into a teardrop shape that extends radially beyond a pinch location created by relative axial movement of adjacent support members coming closer together. A sealing element extends radially during the deployment of the extrusion barriers and is contained between them. The extension of the extrusion barriers allows conformance to surface irregularities in the surrounding tubular or wellbore wall. | 06-13-2013 |
