| titleOfInvention | Packer assembly |
| abstract | Abstract of the Disclosure A downhole packer assembly includes a first packer tool with a flexible tubular packer body which is radially extend-able by virtue of fluid pressure in a packer set chamber. A generally annular packer foundation, including an upper packer head, is connected to the upper end of the packer body. The tool defines a bypass flow system for permitting flow of fluid from the packer set chamber to a central longitudinal flowway of the assembly and from this central flowway to the exterior of the assembly. A control sub adjacent the packer foundation is movable with respect to the packer foundation between a first position, for opening the bypass system, and a second position, closing the bypass system. The control sub is preferably further operative, in its first position, to permit communi-cation between the central flowway and the packer set chamber, and in its second position, to close the packer set chamber. A second packer tool is connected in tandem with the first tool. A ported cylinder is communicatively connected to the packer foundations generally below the locus of the control sub and has a piston reciprocably disposed therein and sealed with respect thereto, the piston being yieldably urged toward the control sub. A plug ejector may be adjoined to the upper packer head of the first tool and disposed therein but adapted to permit flow therethrough. The plug ejector has a free end extending upwardly and positioned for telescopic movement with respect to the lower end of the control sub as it moves between its inflation and set positions. |
