The patent application (Publication Number: US20240003231A1) describes an apparatus designed for perforating a wellbore efficiently. The apparatus consists of multiple perforator units, including a first and a second perforator unit, connected by a signal transfer module. This module comprises an enclosure with an initiator, igniter, fuse, and isolator, all working together to generate high order output for perforation. The isolator secures the fuse within the enclosure using shock attenuators, ensuring effective transmission of motion between components.
Furthermore, the apparatus includes a holder for the fuse and a plug connected to the enclosure, maintaining a gap between the fuse and the enclosure's inner surface. The shock attenuators, with specific modulus of elasticity, facilitate the smooth transfer of motion within the apparatus. The isolator's design, with the plug and shock attenuators, ensures the safe and efficient operation of the perforating apparatus. Additionally, the initiator is described as a sealed initiator, adding to the safety and reliability of the overall system. Overall, the patent application outlines a well-thought-out apparatus for perforating wellbores, emphasizing safety, efficiency, and reliability in its design and operation.
