OSTI ID:6686337
An inflatable packer for use in wells employs disconnectable clamping means for connecting a resilient inflatable sleeve element of the packer to the body of the packer to make for ease of assembly and disassembly of the packer under field conditions. An elongated resilient sleeve is positioned over a tubing section. Clamping means are provided to connect the ends of the sleeve in air-tight relationship to the tubing section. Means are provided to inflate the sleeve to cause it to expand. The clamps are disconnectable at one end of the resilient sleeve. A mandrel section having a central opening to slideably receive the tubing section is provided with serrations on the outside of one end for engagement inside the resilient sleeve. A compressible sleeve having inner serrations fits over the mandrel section and engages the outside of the end of the resilient sleeve. A tapered collar slideably engages over the compressible sleeve. (4 claims)
