Abstract
A hydraulically set well packer. The setting sleeve is releasably locked to the packer mandrel to prevent premature setting while the packer is being lowered to its desired downhole location. The setting sleeve is unlocked by increasing fluid pressure within the packer mandrel above a preselected value. The length of the setting sleeve can be easily adjusted to accommodate additional piston units, changes in mandrel length, and various packing elements.
