Fluid pressure actuated perforating gun
Patent
·
OSTI ID:6368045
A well perforating gun assembly includes a perforating gun secured to the bottom of a tubular actuating housing containing a fluid pressure actuated hammer and a fixedly mounted primer against which the firing means is impacted. A latch normally maintains the firing means in an elevated position with respect to the primer but such latch may be released through the application of sufficient fluid pressure force to the firing means to drive it into engagement with the primer. If the primer fails to ignite, a second fluid pressure force is employed to move the firing means to its original latched position, ready for a second application of fluid pressure to release the firing means and again impact the primer.
