Force fit inflatable packer clamp
Patent
·
OSTI ID:6798688
A force-fit clamp for use in a field-dressable inflatable packer for use in wells is described. A removable resilient sleeve is connected on a tubular member by the force-fit clamp. A mandrel section having a central opening to slideably receive the resilient sleeve is provided with serrations in the outside of one end for engagement inside the resilient member. A force-fit sleeve having inner annularly extending protuberances force fits over the mandrel section and engages against the outside of the end of the resilient sleeve. As the collar is forced down on the resilient sleeve, the sleeve is compressed between the outside of the mandrel section and the inside of the forcefit sleeve. The resilient sleeve is thus connected between the mandrel section and the force-fit sleeve. Means are provided to maintain the sleeve and the mandrel section in position with respect to the tubing section to provide a suitable inflatable packer for field use. (7 claims)
