Abstract
A perforating gun (10, 210, 310, 410) is provided for retaining a plurality of explosive charges (16, 16') in an angular phased array with the discharge ends (16a, 16a') of each succeeding explosive charge (16, 16') disposed at a selected angular orientation relative to the other explosive charges (16, 16') as determined by the configuration of an undulating path defined by support wires (14, 14') or wire pairs (19a, 19b). The perforating gun (10, 210, 310, 410) comprises a plurality of support wires (14, 14') disposed about a common longitudinal axis (L--L) and extending in an undulating path so as to define a wire carrier or cage in which the explosive charges (16, 16') are retained by securing the discharge ends (16a), or the initiation ends (16b), or both, to support wires (14, 14). The undulating path of the support wires (14, 14') disposes the explosive charges (16, 16') in the angular orientation selected by selecting the pitch of the spiral-twisted support wires (14) of the retainer cage.
