ABSTRACT:
An inflatable packer is provided for introduction into a subterranean well bore on a conduit. A pinch can form in the inflatable elastomeric bladder of the packer during inflation or deflation, forming a seal which obstructs the effective passage of pressured fluid, thereby obstructing inflation and deflation of the bladder. Additionally, ribs on the exterior of the bladder can cut into the bladder during nonuniform inflation or deflation of the bladder. The packer provides a series of shape-controllers to cause uniform inflation along the length of the bladder to eliminate these problems.
