  • Patent number: 4796707
    Abstract: An apparatus is provided for running in, actuating, and retrieving an inflatable packer or bridge plug of the type which may be passed through a small diameter tubing, sealed against a large diameter well casing by passing fluid to the packer through a remedial tubing to inflate an elastomeric packing element, and then be retrieved to the surface through the small diameter tubing by deflating the elastomeric packing element. Circulation may be maintained during run-in through an open port in a centralizer member provided on the bottom of the packer or bridge plug. If the device is used as a bridge plug, the open port is closed by a sleeve valve which in turn is actuated by a secondary mandrel extending to the top of the tool for removal by wireline. Removal of the secondary mandrel prior to deflation opens a second port in the centralizing member providing equalization of pressure above and below the inflated elastomeric element.
