Abstract

A packer apparatus with a circulating port. A housing of the packer has inflation passages, circulating passages, treating fluid passages, and equalizing passages defined therein. In a straddle packer embodiment, upper and lower packers are mounted on the housing on opposite sides of an outlet of the treating fluid passage. A circulation valve with a sliding differential pressure actuated valve sleeve is disposed below the packers. An inner mandrel is slidably received in the central opening of the housing. The mandrel has a mandrel bore and has upper inflation and circulating ports, lower inflation ports, upper and lower equalizing ports, a treating port and lower circulating ports, all of which communicate with the mandrel bore. The valve sleeve has a valve port. 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 reciprocation without rotation of the mandrel relative to the housing. The mandrel may also be used to lock the valve sleeve in a closed position. The lug and J-slot define a repeatable sequence of inflating (or deflating) position, intermediate position, circulating 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.
