摘要：A compression assembly () for actuating packing elements of a through tubing
bridge plug in a casing string of a wellbore. The compression assembly () includes asupport assembly () and an anti extrusion assembly (). The support assembly () has arunning configuration in which link arm assemblies are substantially longitudinallyoriented and an operating configuration in which short arms () are pivoted relative tolong arms () of link arm assemblies such that the short arms () form a support platform.The anti extrusion assembly () is operably associated with the support assembly (). Theanti extrusion assembly () has a running configuration in which petals () are substantiallyperpendicular to a base member () and nested relative to one another and an operatingconfiguration in which the petals () are radially outwardly disposed substantially fillinggaps between the short arms ().
