摘要： An apparatus for use in a subterranean well includes a downhole energy source, a first switch, a second switch, a detonator, a first controller and a second controller. The first switch has a first predetermined state to transfer energy from the energy source, and the second switch has a second predetermined state to transfer the energy from the energy source. A detonator receives the energy from the energy source when the first switch and second switches are concurrently in the first and second predetermined states. A first controller independently detects a predetermined stimulus that is transmitted from the surface of the well and causes the first switch to enter to first predetermined state based on the detection by the first controller. A second controller independently detects the predetermined stimulus transmitted from the surface of the well and causes the second switch to enter the second predetermined state based on the detection by the second controller.

摘要： Embodiments of the invention include methods and systems for perforating a well using a wired work string assembly. According to embodiments of the invention, the method includes positioning a wired work string assembly in a wellbore, the work string assembly comprising a plurality of wired pipe communicatively coupled at each joint, a depth correlation tool, and a perforating gun assembly. A depth of the perforating gun assembly is determined from a depth correlation tool positioned within the wellbore, and an electrical signal related to the depth of the perforating gun assembly is transmitted to a surface above the wellbore. Firing of the perforating gun assembly is initiated via a signal transmitted from the surface above the wellbore. An electrical signal from the wellbore is transmitted to the surface to confirming the firing of perforating gun assembly. The system includes various tools for perforating the well using the disclosed methods.
