摘要

A sensing and data recording downhole system and method for monitoring of firing of a perforating gun system in a well, including a perforating gun system having charges or bullets for performing well perforation; and at least one of one or more downhole recorders and one or more fluid detection sensors located above, along, below or in array on the perforating gun system or inside the perforating gun system on a conveyance and configured to at least one of record sound waves generated by explosions of the charges or bullets during the firing of the perforating gun system and detect a presence of fluid within a body of the perforating gun system before and after guns of the perforating gun system are fired.
