Perforating gun with internal shock mitigation

Abstract

A perforating gun can include at least one explosive component, and a shock mitigation device including a shock reflector which indirectly reflects a shock wave produced by detonation of the explosive component. Another perforating gun can include a gun housing, at least one explosive component, and a shock mitigation device in the gun housing. The shock mitigation device can include a shock attenuator which attenuates a shock wave produced by detonation of the explosive component. Yet another perforating gun can include a shock mitigation device with an explosive material which produces a shock wave that interacts with another shock wave produced by detonation of an explosive component in a gun housing.

         13 . A perforating gun, comprising:
 a gun housing;   at least one explosive component; and   a shock mitigation device in the gun housing, the shock mitigation device including a shock attenuator which attenuates a shock wave produced by detonation of the explosive component.   
     
     
         14 . The perforating gun of  claim 13 , wherein the shock mitigation device reflects the attenuated shock wave. 
     
     
         15 . The perforating gun of  claim 13 , wherein the shock mitigation device absorbs, breaks-up, scatters or disperses the shock wave. 
     
     
         16 . The perforating gun of  claim 13 , wherein the shock attenuator comprises layers of resilient and non-resilient materials. 
     
     
         17 . The perforating gun of  claim 13 , wherein the shock attenuator comprises variations in acoustic impedance.
