Casing bore receptacle
A sealing assembly comprising a casing bore receptacle, an annular packoff member, and a tubing carried mandrel for use in establishing sealing integrity between a fluid transmission conduit or tubing and an outer conduit or casing, is disclosed. The casing bore receptacle is incorporable in the casing and the annular packoff member is initially carriable on the mandrel. Seals on the and exterior of the packoff member establish a seal with the mandrel and the casing. Upon abutting engagement of the packoff member with the casing bore receptacle, a collet on the packoff member is released from the mandrel and cammed radially outward into engagement with the casing bore receptacle to anchor the packoff member to the casing bore receptacle. The mandrel can then move relative to the packoff member and the casing. A lock support sleeve is positioned intermediate the mandrel and the latching arms of the collet. Radially shiftable locking dogs carried by the lock support sleeve are engaged with a mandrel recess during run-in, with the collet arms in the anchored position, and with the body of the annular packoff during retrieval.
