ABSTRACT:
A long stroke packer for use in a well bore. The packer has a housing assembly with an operating mandrel assembly disposed therein. A packer mandrel assembly is slidably connected to the housing assembly. During operation, the operating mandrel assembly may be actuated to cycle a tool below the packer without setting the packer. After the operating mandrel assembly and housing assembly are moved a predetemined amount with respect to the packer mandrel assembly, the housing assembly is brought into contact with a sliding shoe on the packer mandrel assembly which in turn engages and deforms packer elements into sealing engagement with the well bore.
