Abstract

The present disclosure relates to methods for perforating wells. A method in accordance with one embodiment includes positioning a perforating gun in the well and detonating the shaped charge in the well. The perforating gun includes a shaped charge that 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 having a spheroidized metal powder.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . 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, a liner disposed within an opening of the casing, and an explosive disposed between the casing and the liner, wherein the liner is made of a metal powder blend that comprises a spheroidized metal powder; and   detonating the shaped charge in the well.   
     
     
         2 . The method of  claim 1 , wherein the spheroidized metal powder comprises a spheroidized tungsten powder. 
     
     
         3 . The method 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, graphite, and a combination thereof. 
     
     
         4 . The method of  claim 2 , wherein the metal powder blend further comprises normal tungsten powder. 
     
     
         5 . The method of  claim 2 , wherein the metal powder blend comprises greater than about 80 wt % of tungsten.
