Abstract
The present disclosure relates to a shaped charge. The shaped charge includes an explosive component and a liner member coupled to the explosive component. The explosive component and the liner member emit a perforating jet based on ignition of the explosive component. The liner member has a planar symmetric portion that is planar symmetric along an axial length of the planar symmetric portion relative to planes perpendicular to a direction of the emitted perforating jet.
Claims20
A shaped charge, comprising:
- a casing;
- an explosive component disposed inside of the casing;
- and
- a liner member disposed inside of the explosive component, wherein the explosive component and the liner member are configured to emit a perforating jet based on ignition of the explosive component, wherein the liner member has a planar symmetric portion that is planar symmetric along an axial length of the planar symmetric portion relative to planes perpendicular to a direction of the emitted perforating jet, wherein the planar symmetric portion comprises first and second confinement portions disposed at opposing sides of the liner member about a longitudinal axis of the shaped charge, wherein the first and second confinement portions extend along the axial length, and the axial length is at least half of a total axial length of an interior volume of the liner member.

A shaped charge, comprising:
- a casing;
- an explosive component disposed inside of the casing;
- a liner member disposed inside of the explosive component, wherein the explosive component and the liner member are configured to emit a perforating jet based on ignition of the explosive component;
- and
- an external confinement feature disposed inside of the explosive component about the liner member, wherein the external confinement feature is configured to impart a planar symmetry to the shaped charge, the external confinement feature comprises first and second confinement portions disposed at opposing sides of the liner member about a longitudinal axis of the shaped charge, the first and second confinement portions are circumferentially split at a window, and the external confinement feature comprises a coupling rim extending across the window and coupling together the first and second confinement portions.

A method, comprising:
- providing a shaped charge having a casing, an explosive component, and a liner member;
- inducing a planar symmetry in or adjacent the liner member via a planar symmetric portion, wherein the planar symmetric portion comprises first and second confinement portions disposed at opposing sides of the liner member about a longitudinal axis of the shaped charge, the first and second confinement portions extend along an axial length of the planar symmetric portion, the axial length is at least half of a total axial length of an interior volume of the liner member, the first and second confinement portions are separated from one another at first and second circumferential splits being diametrically opposite to one another about the longitudinal axis, and the planar symmetric portion comprises a coupling portion extending across the first and second circumferential splits and coupling together the first and second confinement portions;
- and
- assembling the shaped charge having the casing, the explosive component disposed inside of the casing, and the liner member with the planar symmetric portion disposed inside of the explosive component.
