The invention provides a new strip carrier assembly for carrying shaped charges, such as is particularly useful in perforating guns as are utilized to perforate oil and gas wells. The strip carrier includes a coupling member which couples adjacent strip carrier members together to form a contiguous assembly, and which further provides mounting system for a shaped charge so as to maintain uniform spacing even across the coupling junction. Additionally, the carrier assembly includes a novel tab assembly which cooperates with a charge carrier housing configuration to provide a single assemblage of parts which is capable of orienting shaped charges in any one of a plurality of desired orientations relative to the carrier strip.

A perforating assembly for use in a perforating gun, comprising: a first elongated carrier configured to support a plurality of shaped charges spaced uniformly along the length of said first elongated carrier, said elongated carrier having a predetermined cross-section; a second elongated carrier configured to support a plurality of shape charges spaced uniformly along the length of said second elongated carrier, the spacing between shape charges on said first carrier being generally the same as the spacing of shape charges on said second carrier, said second elongated carrier also having a predetermined cross-section; a coupling plate coupled between said first and second elongated carriers to form an elongated strip assembly, said coupling plate having a first portion extending between first and second elongated carriers, and having second and third portions being laterally offset to one side of said first portion and longitudinally disposed on either end of said first portion, said coupling plate being able to hold at least one shape charge, such that said shape charges on said first carrier, said shape charges on said second carrier, and said at least one shape charge on said coupling plate together form a series of shape charges that are all uniformly spaced apart.
