Abstract:
1. A firing head actuator for a well perforating system comprising: a housing assembly; a first impact piston initially secured to and slidably disposed within the housing assembly; an electronic time delay assembly disposed within the housing assembly; a trigger assembly disposed within the housing assembly; a second impact piston initially secured within and slidably disposed within the housing assembly; and an initiator disposed within the housing assembly, wherein, a pressure signal of a predetermined threshold actuates the first impact piston; wherein, the first impact piston mechanically actuates the electronic time delay assembly; wherein, after a predetermined time period, the electronic time delay assembly sends an electric signal to actuate the trigger assembly; wherein, the trigger assembly mechanically releases the second impact piston; and wherein, pressure shifts the second impact piston into contact with the initiator.
