Abstract
An impact sleeve is used for mitigating damage in a perforating gun resulting from shaped charge detonation. In one example, a perforating gun includes a gun carrier, with a charge holder and the impact sleeve inside the gun carrier. The charge holder holds a plurality of shaped charges capable of being detonated with sufficient explosive energy to generate high-velocity fragments inside the gun carrier. The impact sleeve comprises an energy-absorbing material and optional raised features for absorbing at least some energy of the high-velocity fragments. The materials, raised features, positioning, and geometry of the impact sleeve and raised features may be tuned to optimize energy absorption.
