US12460519 - Perforating gun having modular construction

A technique facilitates perforating operations. According to an embodiment, a perforating gun system utilizes a plurality of modular perforating gun sections which are readily assembled to create a perforating gun with a desired number and orientation of shaped charge holders. In some applications, the modular perforating gun sections may be formed of plastic, e.g. injection moldable plastic, to further reduce costs and provide great flexibility with respect to construction of the desired perforating gun.

The patent describes a modular perforating gun system designed for well operations, featuring sections that can be easily assembled to achieve various lengths and configurations. These sections may be made from injection moldable plastic, enhancing cost-effectiveness and flexibility in design.

Claim 1

1 . A system for use in a well, comprising: a perforating gun having a plurality of modular perforating gun sections configured to be coupled together to establish a desired length of the perforating gun, at least one modular perforating gun section of the plurality of modular perforating gun sections comprising: a central axis extending along a longitudinal axis of the perforating gun; a planar first end wall positioned proximate to a first end of the at least one modular perforating gun section; a planar second end wall positioned proximate to a second end of the at least one modular perforating gun section; at least one charge holder and charge retainer to receive and retain a corresponding shaped charge; at least one connector positioned on the first end wall and extending outwardly therefrom along the central axis, the at least one connector including a hook; at least one opening positioned on the second end wall, the at least one opening configured to receive the at least one connector of an adjacent modular perforating gun section; and at least one protrusion positioned on an interior surface of the second end wall, the at least one protrusion configured to engage the hook of the at least one connector of the adjacent modular perforating gun section. a perforating gun having a plurality of modular perforating gun sections configured to be coupled together to establish a desired length of the perforating gun, at least one modular perforating gun section of the plurality of modular perforating gun sections comprising: a central axis extending along a longitudinal axis of the perforating gun; a planar first end wall positioned proximate to a first end of the at least one modular perforating gun section; a planar second end wall positioned proximate to a second end of the at least one modular perforating gun section; at least one charge holder and charge retainer to receive and retain a corresponding shaped charge; at least one connector positioned on the first end wall and extending outwardly therefrom along the central axis, the at least one connector including a hook; at least one opening positioned on the second end wall, the at least one opening configured to receive the at least one connector of an adjacent modular perforating gun section; and at least one protrusion positioned on an interior surface of the second end wall, the at least one protrusion configured to engage the hook of the at least one connector of the adjacent modular perforating gun section. a central axis extending along a longitudinal axis of the perforating gun; a planar first end wall positioned proximate to a first end of the at least one modular perforating gun section; a planar second end wall positioned proximate to a second end of the at least one modular perforating gun section; at least one charge holder and charge retainer to receive and retain a corresponding shaped charge; at least one connector positioned on the first end wall and extending outwardly therefrom along the central axis, the at least one connector including a hook; at least one opening positioned on the second end wall, the at least one opening configured to receive the at least one connector of an adjacent modular perforating gun section; and at least one protrusion positioned on an interior surface of the second end wall, the at least one protrusion configured to engage the hook of the at least one connector of the adjacent modular perforating gun section.
