Patent

CA 2021310

A straddle packer apparatus includes a housing having a central opening. The housing has inflation passages, treating fluid passages, and equalizing passages defined therein. Upper and lower longitudinally spaced packers are mounted on the housing on opposite sides of an outlet of the treating fluid passage. An inner mandrel is slidably received in the central opening of the housing. The mandrel has a mandrel bore and has upper and lower inflation ports, upper and lower equalizing ports, and a treating port, all of which communicate with the mandrel bore. A lug and endless J-slot is operably associated with the housing and mandrel for controlling a telescoping position of the mandrel relative to the housing in response to telescoping reciprocation without rotation of the mandrel relative to the housing. The lug and J-slot define an endlessly repeating sequence of inflating position, treating position, equalizing position, and ready position wherein the tool is ready to return to the original inflating position on the next telescoping stroke of the mandrel within the housing.
