摘要： A perforating gun assembly for use in a wellbore. The perforating gun assembly includes a carrier gun body and a charge holder disposed within the carrier gun body. A plurality of shaped charges are supported within the carrier gun body. A secondary pressure generator is operably associated with at least one of the shaped charges. The secondary pressure generator optimizes the wellbore pressure regime immediately after detonation of the shaped charges by controlling the dynamic underbalance created by the empty gun chambers to prevent excessive dynamic underbalance which may detrimentally effect the perforating operation.

摘要： By using reactive shaped charges to perforate failure prone formations, the present invention is able to keep formation sand in place and increase productivity. An efficient flow distribution is surprisingly produced without requiring surge flow or post-perforation stimulation. Further, using the secondary reactive effects of reactive shaped charges allows for the reduction of the risk of erosion and minimization of sand production. In a preferred embodiment, a liner capable of producing a strongly exothermic intermetallic reaction between liner components within and around the tunnel is used to achieve a high percentage of substantially clean and enlarged perforation tunnels conducive to flow or gravel packing.

摘要： A perforating gun includes a charge tube having shaped charges affixed thereto. Each shaped charge includes a radially outward pointing post adapted to receive a detonator cord. A retention member installed on the post provides a compressive force that energetically couples the detonator cord to the post. The radially outermost portion of the retention member is radially flush with or radially recessed relative to the radially outermost portion of each post. In one embodiment, the retention member has a rounded medial portion, a central opening and a pair of locking tabs that point radially inward to the central opening. Each post may include a slot for receiving the detonator cord and a circumferential groove that is adapted to receive the locking tabs.
