ABSTRACT:
An inner string cementing adapter for use in cementing a casing in a well bore. The adapter comprises a mandrel which may be attached to a lower end of a work string and a seal assembly positioned adjacent to the mandrel. The seal assembly is designed for sealing engagement with a substantially flat upper surface of floating equipment in the casing. A seal retainer is provided for retaining the seal assembly on the mandrel. The seal assembly comprises a reinforcing insert positioned adjacent to a downwardly facing surface of the mandrel and an elastomeric seal attached to a downwardly facing surface of the insert. The seal is sized such that the outside diameter thereof is larger than a central opening defined in the floating equipment. An inner string cementing tool using the adapter and a method of inner string cementing are also disclosed.
