ABSTRACT:
A subterranean well tool such as a packer and attached telescoping seal receptacle assembly is disclosed. The tool is fabricated from a plurality of threaded tubular members and annular deformable rings fabricated of a metal softer than the tubular members are used to establish metal-to-metal sealing integrity between interengagable component members. Upon full engagement, sealing integrity is established along the transverse interface between each tubular member and the deformed seal ring. During initial disengagement, sealing integrity is maintained along a bearing inclined interface between the ring and at least one tubular member adjacent the threaded connection.
