ABSTRACT:
A perforating gun for perforating a section of a well casing in which a plurality of explosive charge units are mounted on an elongated mounting strip in a pattern corresponding to the desired pattern of perforations in the well casing. The areas of the mounting strip that receive the charge units have a greater width than the remaining areas of the strip to provide an increased support surface for the charge units. Each charge unit is formed by a case connected to a cap to provide a housing for the explosive. The cap is crimped to the case to prevent premature detonation of the explosive.
