AI Technical Summary

Technical Problem

Existing shaped charge perforators face challenges from extreme impact loads, hydrostatic pressure, and vortex-induced vibrations in deep-sea environments, resulting in bulky tools, unstable positioning, and the tendency for conventional designs to fail in deep-sea conditions.

Method used

It adopts an impact-resistant shell structure, including a spring rack, impact buffer unit and positioning components. Through internal force balance design and intelligent buffer materials, it offsets impact energy and achieves stable anchoring through central shaft and positioning components.

Benefits of technology

It effectively resists the huge impacts in deep-sea operations, ensures the stability, reliability and positioning accuracy of the perforator under complex well conditions, and avoids problems such as tool displacement and insufficient anchoring force.
