SHAPED CHARGE SYSTEM HAVING MULTI-COMPOSITION LINER |
| 摘要 |
A technique facilitates perforation, including the perforation of a casing and formation. A shaped charge is formed with a case, a liner, and a high explosive material located between the case and the liner. The liner is formed of a powder material, e.g. a powder metal material. The powder material properties of the liner between an apex of the liner and a skirt of the liner may be selectively varied to provide a desired jet velocity and jet mass of the liner upon detonation of the high explosive material. |

1. A system for forming a perforation in a subterranean formation, comprising:
a shaped charge having a case; a liner; and a high explosive pellet positioned between the case and the liner, the liner being formed of a blend of powder materials extending along an interior of the case from an apex to a skirt, the blend of the powder material being varied from the apex to the skirt of the liner. |
