Abstract
An inflatable packer which includes a tubular mandrel with an inflatable sleeve position about and connected to the mandrel by a pair of axially spaced apart collars. The ends of the sleeve are reinforced by reinforcing sheaths which include a plurality of axially extending overlapping expansible ribs which are contained in spaced apart cavities formed adjacent the ends of the sleeve. Ports are provided for allowing well bore fluid to communicate with the cavities to equalize the pressure around and between the ribs so that well bore pressure does not prevent the ribs from expanding.
