ABSTRACT:
The invention comprises an inflatable packer comprising a tubular mandrel having a port extending radially therethrough. An elastomeric valve element is resiliently urged against the exterior of the mandrel to cover the port. A generally tubular packer body surrounds the mandrel and comprises a pair of longitudinally spaced apart heads, one of which is longitudinally slidable on the mandrel, and a tubular radially expandable packer element interposed between the heads. Fluid communication is provided between the radially outer side of the said port and a fluid reception chamber. The packer body is operatively associated with the chamber and responsive to fluid pressure therein to radially extend the packer element.
