DEVICES AND RELATED METHODS FOR ACTUATING WELLBORE TOOLS WITH A PRESSURIZED GAS

摘要

An apparatus for activating a wellbore tool may include a first sub having a an igniter disposed in the first chamber, the igniter generating a flame output when ignited and a power charge disposed in the second chamber, the power charge generating a high pressure gas when ignited by the flame output The well tool also includes a gas transfer sub connectable with the first sub, the gas transfer sub having: a first end receiving a portion of the power charge, a longitudinal bore, and a plurality of flow passages radiating from the longitudinal bore, the plurality of flow passages providing fluid communication between the longitudinal bore and the second chamber of the first sub; and a second sub connectable with the gas transfer sub.
