Downwhole packer apparatus and method of limiting packer element extrusion

摘要: An improved downhole tool apparatus and method for limiting the extrusion of packer element seals packers bridge plugs which utilize segmented retaining shoes when such tools are larger diameters, or used at elevated differential pressures temperatures. Preferably incorporate a plurality gap-bridging disks to limit if not eliminate unwanted elements upon setting tool. By making non-metallic material, subject invention increases ability drill mill out well bore in less time than it would take with using conventional non-conventional drilling milling techniques equipment while providing enhanced high temperature pressure performance, especially nominal outside diameter tools.
