摘要： A bridge plug having a segmented backup shoe, and at least one split cone extrusion limiter, the extrusion limiter comprising a two part conical retainer positioned between packer elements and the segmented backup shoe to block packer element extrusion though spaces between backup shoe segments. In one embodiment, two split cone extrusion limiters are used together and positioned so that each split cone extrusion limiter covers gaps in the other extrusion limiter and together the two split cone extrusion limiters block packer element extrusion though gaps between backup shoe segments regardless of their orientation relative to the segmented backup shoe. In one embodiment, a solid retaining ring is positioned between a split retaining cone extrusion limiter and a packer element and resists extrusion of packer elements into spaces in the split cone extrusion limiter or limiters.
