ABSTRACT:
The completion tool is formed by two identical inflation valve bodies, two identical casing members screwed to the two valve bodies respectively, two identical packer mandrels with packers coupled to said inflation valve bodies, and a valve sleeve coupled to the other ends of the two casing members and to the two packer mandrels. A piston is slidably located in the sleeve valve for movement between opened and closed positions. One casing, with its valve body and packer mandrel and packer is screwed to one end of the sleeve valve and the other casing with its valve body and packer mandrel and packer is coupled to the other end of the sleeve valve by way of an adapter coupling. The packers are bonded in annular slots formed in the packer mandrels at opposite ends to allow the packers to be expanded outward. Valve structure is provided in the valve bodies for allowing the packers to be inflated. A central passageway and outer by-pass passageway are formed through the completion tool. The piston has ports formed therethrough which are in fluid communication with ports formed through the sleeve valve when the piston is in its open position for providing a flow path from the outside of the tool to the inside by way of the ports and the piston. The inside of the sleeve valve carries spring biased detents which engage upper and lower slots for releasably holding the piston in its closed and open positions, controlling the shifting force of the piston.
