OSTI ID:6505203
An hydraulic packer assembly for sealing an annulus between a well casing and a tubing string inserted within the well casing comprises a packer and a setting tool. The packer includes a packer body having an internal bore with a seal and gripping members mounted on its exterior surface for engaging the interior surface of the well casing. Actuating mechanisms are provided within the packer for expanding the seal and gripping members into contact with the casing wall, which mechanisms include a piston and cylinder arrangement operated by fluid pressure conveyed from the tool interior to the cylinder. The setting tool is releasably coupled to the packer body to mount it on a tubing string and for conveying fluid pressure to the actuating mechanisms. Seals on the setting tool provide a fluid tight seal between the setting tool and the axial bore through the packer body.
