Abstract
A method and apparatus for containing one or more shaped charges in a single plane, arrayed about the center axis of a gun body, and detonated from a single initiator in a shaped charge cluster assembly.
Claims52
A perforating gun comprising:
- an outer gun body;
- a first cluster charge holder;
- a plurality of shaped charges having an open end and an apex end;
- an initiating device;
- wherein the first cluster charge holder comprises:
- a top end, a bottom end, a housing axis extending from the center of the top and an outer surface substantially parallel to the housing axis;
- a central bore extending from the top end of the charge housing along the housing axis;
- a plurality of charge cavities in the charge housing arranged radially about the housing axis, each of the charge cavities extending from a shaped charge aperture in the outer surface toward an apex end proximate the central bore;
- a plurality of priming holes in the charge housing connecting the central bore to the plurality of charge cavity apex ends;
- wherein the initiating device is inside the central bore of the first cluster charge holder and the plurality of shaped charges are inside the plurality of charge cavities;
- and
- wherein the explosive output of the initiating device detonates the shaped charges.

A perforating gun assembly comprising:
- a first cylindrical body composed of an electrical insulator having a plurality of orthogonal hollow cutouts in a first orthogonal perforation plane, each hollow cutout further containing a plurality of shaped chares, one disposed in each cutout;
- and
- a first detonator disposed within the center of the cylindrical body, wherein the shaped charges perforated in the first orthogonal plane when detonated by the first detonator.
A method for loading a perforating gun comprising:
- installing a first charge cluster composed of an electrical insulator material and having a plurality of shaped charge holders oriented in a first orthogonal perforating plane;
- installing a plurality of shaped charges into the charge cluster;
- installing a first detonator into the center of the first charge cluster;
- and
- installing the charge cluster into a perforating gun body, wherein the shaped charge cluster is snapped together using a plurality if tabs.
