High temperature packer for well conduits
A packer for a subterranean well having a casing extending through a production zone requiring steam treatment to improve fluid production from such zone is described comprising: an inner tubular body assembly having connector means at its upper end for detachable threaded connection to the bottom of an insulated tubing string; and outer tubular body assembly mounted in surrounding relationship to the inner tubular body assembly; means for setting the packer by engaging the slips with the casing wall and deforming the external packing element into sealing engagement with the casing wall; an inner packing assembly of non-elastic, high temperature resistant materials axially compressed in the internal annular recess; and a tubular mandrel connectable at its upper end to the insulated tubing string.
