초록 ▼

A subterranean well tool is run through a well bore tubular and includes a well plug having an expandable elastomer member. An articulating anti-extrusion support system is provided for the well plug to resist extrusion of the elastomer. The system includes upper and lower platforms which are shiftable outwardly by a control mandrel. The platforms support extrusion resistors in the form of a series of crushable plates over which companion flexible cups are disposed and provide blade elements which may be flexibly positioned for inter-alignment around wing portions of the crushable plates for resistance of elastomeric extrusion. An elastomer member may include a series of spirable elastomeric sealing rings which, upon application of compressive load through the mandrel, expand in a helixical configuration through truncation initiation.

[ What is claimed and desired to be secured by Letters Patent is:] [8.]8. A subterranean well tool, comprising:(a) an elastomeric seal assembly having first and second ends and outwardly expandable to a set position by compressive hydrostatic stress applied substantially simultaneously through each end of said assembly;(b) means for applying the compressive hydrostatic stress to said seal assembly to move said seal assembly to said set position; and(c) energy storage means chargeable by the compressive stress applied to the seal assembly during movement to the set position and thereafter being dischargeable to transmit said stored compressive stress into the seal assembly for retaining integrity of said seal assembly in the initial set position.
