Extrusion limiting ring for wellbore isolation devices

A wellbore isolation device includes an elongate mandrel, a sealing element carried by the mandrel, and a slip wedge positioned about the mandrel axially adjacent the sealing element and providing an outer radial surface. A set of slip segments is circumferentially disposed about the mandrel and at...

Zusammenfassung:A wellbore isolation device includes an elongate mandrel, a sealing element carried by the mandrel, and a slip wedge positioned about the mandrel axially adjacent the sealing element and providing an outer radial surface. A set of slip segments is circumferentially disposed about the mandrel and at least a portion of the slip wedge. An extrusion limiting ring has an annular body that provides a first axial end, a second axial end, and a scarf cut extending at least partially between the first and second axial ends. The extrusion limiting ring is movable between a contracted state, where the extrusion limiting ring is disposed about the sealing element, and an expanded state, where the extrusion limiting ring is disposed about the outer radial surface of the lower slip wedge.
