Abstract
A setting assembly tool suitable for suspension in a subterranean well by a wireline is provided for activating an inflatable packer. A downhole firing head with a combustion device is utilized for generating downhole a high fluid pressure in a passageway of the setting assembly tool, with the passageway being in fluid communication with the packer for setting the packer. In response to a pressure buildup of a predetermined level, fluid pressure is dumped from the passageway to the well while a check valve closes to retain the packer in the set position. To deactivate the retrievable packer, a conventional fishing tool supported by a wireless may be used to exert an axial force on a housing sufficient to move the housing relative to the packer and open a fluid port for discharging liquid from the packer. The setting assembly tool may be retrieved to the surface via the wireline immediately after the packer is set.
