Abstract

Claims (31)

1. 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 first cluster charge holder 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;

a detonator circuit recessed into the first cluster charge holder, wherein the detonator circuit is electrically coupled to the initiating device; and

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.

2. The perforating gun of claim 1 further comprising:

a second cluster charge holder;

a plurality of shaped charges having an open end and an apex end;

a detonation transfer device;

wherein the second 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 detonation transfer device is inside the central bore of the second cluster charge holder and the plurality of shaped charges are inside the plurality of charge cavities of the first and second cluster charge holders;

wherein an explosive output of the initiating device detonates the shaped charges in the first cluster charge holder and the detonation transfer device; and

wherein an explosive output of the detonation transfer device detonates the shaped charges in the second cluster charge holder.

3. The perforating gun of claim 2 wherein the detonation transfer device further comprises a booster.

4. The perforating gun of claim 2 wherein the detonation transfer device further comprises detonating cord.

5. The perforating gun of claim 1 wherein the detonator circuit further comprises an addressable switch.

6. The perforating gun of claim 1 wherein the initiating device further comprises a detonator.

7. The perforating gun of claim 1 wherein the initiating device further comprises a percussion initiator.
