ABSTRACT:
An assembly for use in establishing sealing integrity between an inner and outer conduit in a subterranean well is disclosed. A multi-component seal assembly having a plurality of individual seal units is assembled on the exterior of an inner tubular conduit for insertion into the bore of an inplace tubular seal receptacle located in a subterranean well. The tubular conduit and associated seal assembly can be inserted into the bore and axial reciprocation of the tubular conduit relative to the seal receptacle is possible without damage to vee-shaped primary elastomeric sealing elements during insertion, while sealing integrity is maintained within the seal receptacle and during unloading and removal of the seals from the seal receptacle.
