CA 2186546

A firing head for actuating an explosive charge in a perforating gun. A firing pin is positioned within the firing head housing to actuate a booster charge leading to the perforating gun. The firing pin can be actuated by mechanical techniques, by controlling the differential pressure between the housing pressure and the well pressure, and by controlling the absolute fluid pressure inside the housing. A release pin initially secures the firing pin, and the release pin can be mechanically actuated. The release pin is also releasably engaged with a differential piston that communicates with the well pressure through a port in the firing head housing. Increases in the housing fluid pressure moves the piston and attached release pin to release the firing pin into contact with the booster charge. Alternatively, the port can be plugged to permit absolute pressure actuation of the firing pin.
