Abstract
Official abstract text for this publication.
A shaped charge includes a casing, a liner disposed within an opening of the casing and an explosive disposed between the casing and the liner. The liner is made of a metal powder blend that includes a spheroidized metal powder. The spheroidized metal powder includes a spheroidized tungsten powder. The metal powder blend may further include a binder and a lubricant. The binder includes copper or lead. The lubricant includes graphite.
First claim
Opening claim text (preview).
What is claimed is: 1. A shaped charge, comprising: a casing comprising spheroidized metal powder; a liner disposed within an opening of the casing; and an explosive disposed between the casing and the liner, wherein the liner is formed by pressing graphite and a metal powder blend that comprises a spheroidized metal powder into a conical shape. 2. The shaped charge of claim 1 , wherein the spheroidized metal powder comprises a spheroidized tungsten powder. 3. The shaped charge of claim 2 , wherein the metal powder blend further comprises one selected from the group consisting of copper, lead, zinc, tin, aluminum, nickel, antimony, cobalt, zinc alloys, tin alloys, aluminum alloys, and a combination thereof. 4. The shaped charge of claim 2 , wherein the metal powder blend further comprises normal tungsten powder. 5. The shaped charge of claim 2 , wherein the metal powder blend comprises greater than about 80 wt % of tungsten. 6. A method for manufacturing a shaped charge, comprising: obtaining a spheroidized metal powder; and preparing a shaped charge comprising: a casing comprising spheroidized metal powder; a liner disposed within an opening of the casing; and an explosive disposed between the casing and the liner, wherein the liner is formed by pressing graphite and a metal powder blend that comprises a spheroidized metal powder into a conical shape. 7. The method of claim 6 , wherein the spheroidized metal powder comprises a spheroidized tungsten powder. 8. The method of claim 7 , wherein the metal powder blend further comprises one selected from the group consisting of copper, lead, zinc, tin, aluminum, nickel, antimony, cobalt, zinc alloys, tin alloys, aluminum alloys, graphite, and a combination thereof. 9. The method of claim 7 , wherein the metal powder blend further comprises normal tungsten powder. 10. The method of claim 7 , wherein the metal powder blend comprises greater than about 80 wt % of tungsten. 11. A method for perforating a well, comprising: positioning a perforating gun in the well, wherein the perforating gun comprises a shaped charge that comprises: a casing comprising spheroidized metal powder, a liner disposed within an opening of the casing, and an explosive disposed between the casing and the liner, wherein the liner is formed by pressing graphite and a metal powder blend that comprises a spheroidized metal powder into a conical shape; and detonating the shaped charge in the well. 12. The method of claim 11 , wherein the spheroidized metal powder comprises a spheroidized tungsten powder. 13. The method of claim 12 , wherein the metal powder blend further comprises one selected from the group consisting of copper, lead, zinc, tin, aluminum, nickel, antimony, cobalt, zinc alloys, tin alloys, aluminum alloys, graphite, and a combination thereof. 14. The method of claim 12 , wherein the metal powder blend further comprises normal tungsten powder. 15. The method of claim 12 , wherein the metal powder blend comprises greater than about 80 wt % of tungsten.
