Inflatable well packers
This patent describes an inflatable well packer. It comprises: a cylindrical mandrel; a packer element comprising substantially tubular inner and outer elastomeric plies coaxially mounted on the mandrel, a protective sheath surrounding the inner ply which sheath is capable of resisting the forced extrusion of the elastomeric material of the inner ply therethrough, and a reinforcing sleeve intermediate the protective sheath and the outer ply; and coupling assemblies cooperatively coupling respective ends of the reinforcing sleeve to the mandrel. Each of the coupling assemblies including inner and outer ring members coaxially mounted on the mandrel with facing surfaces defining an annular space for receiving the adjacent ends of the reinforcing sleeve and wedge member means positioned in the annular space for securing ends of the reinforcing sleeve between the inner and outer ring members.
