Abstract
A system for inflating an inflatable packer located in a well bore on a liner where the inflatable packer has an inflation valve and a latching recess. An inflation tool with inner and outer assemblies is disposable by a string of tubing to a position within the inflatable packer where cup members on the outer assembly straddle the inflation valve and friction drag block members on the outer assembly are located in an annular recess above the inflation valve. An automatic J-slot interconnects the inner and outer assemblies so that the inner assembly can be repetitively moved between an intermediate, a lower and an upper location to open and close flow ports for a valve in the inner and outer assemblies with the value being in fluid communication with the inflation packer in the lower location and where the drag blocks are locked into the recess while the inner assembly is in the lower location and where the valve is closed in the intermediate and the upper locations; so that multiple inflations of multiple inflatable packers can be accomplished with one trip in the well bore.
