EXPANDABLE TRANSLATING JOINT

摘要

An expandable translating joint comprises a first expandable tubular member having a lower end with a recessed inner wall portion and a second expandable tubular member having an upper end with a recessed outer wall portion. The second expandable tubular member is partially disposed within the first expandable tubular member such that the recessed inner wall portion at least partially surrounds the recessed outer wall portion. A retainer is coupled to the recessed inner wall portion of the first expandable tubular member and disposed within the recessed outer wall portion of the lower second expandable tubular member. An expansion cone is operable to move axially through and radially expand the first and second expandable tubulars. The first expandable tubular can translate relative to the second tubular member both before and after expansion.
