Abstract
A liner for a shaped charge is formed from a powder blend and dimensioned for forming a perforating jet to create a hole in a target in response to detonation of an explosive. The powder blend includes an erosion resistant material. The erosion resistant material is a powdered carbide material, a powdered nitride material, or a cobalt powder material.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A liner for a shaped charge, the liner comprising:
an apex portion; and a skirt portion extending outwardly from the apex portion, the liner dimensioned for forming a perforating jet in response to initiation of the shaped charge to create a hole in a target, wherein the liner is formed from a powder blend including an erosion resistant metal powder.
2 . The liner according to claim 1 , wherein the erosion resistant metal powder is a carbide material, a nitride material, or a cobalt material.
3 . The liner according to claim 1 , wherein the erosion resistant metal powder is tungsten carbide.
4 . The liner according to claim 1 , wherein the powder blend further includes a binder.
5 . The liner according to claim 4 , wherein the binder includes a mixture of powdered aluminum and powdered nickel.
6 . The liner according to claim 4 , wherein the binder includes a polymer material.
7 . The liner according to claim 1 , wherein the liner is conically shaped.
8 . The liner according to claim 1 , wherein the powder blend further includes a lubricant.
9 . A shaped charge for reducing erosion of perforation holes, comprising:
a shell; an explosive positioned within the shell; and a liner positioned within the shell, wherein the liner is formed from a powder blend and is dimensioned for forming a perforating jet to create a hole in a target in response to detonation of the explosive and the powder blend includes an erosion resistant metal powder.
10 . The shaped charge according to claim 9 , wherein the erosion resistant metal powder is a carbide material, a nitride material, or a cobalt material.
11 . The shaped charge according to claim 9 , wherein the erosion resistant metal powder is tungsten carbide.
12 . The shaped charge according to claim 9 , wherein the powder blend further includes a binder.
13 . The shaped charge according to claim 12 , wherein the binder includes at least one of powdered aluminum, powdered nickel, a polymer material, and graphite.
14 . The shaped charge according to claim 9 , wherein the liner is conically shaped.
15 . The shaped charge according to claim 9 , wherein the powder blend further includes a lubricant.
16 . The shaped charge according to claim 9 , wherein the liner is configured for depositing the erosion resistant material around and within the hole.
17 . A method for reducing erosion of perforation holes, comprising:
providing a shaped charge, wherein the shaped charge includes a shell and a liner and an explosive positioned within the shell, wherein the liner is formed from a powder blend including an erosion resistant material and is dimensioned for forming a perforating jet in response to detonation of the explosive; deploying the shaped charge in a wellbore; detonating the explosive; creating a first hole in a first target with the perforating jet; and depositing the erosion resistant material around and within the hole.
18 . The method according to claim 17 , wherein the erosion resistant material includes a powdered carbide material, a powdered nitride material, or a cobalt powder material.
19 . The method according to claim 17 , wherein the first target is a wellbore casing.
20 . The method according to claim 19 , further comprising creating a second hole with the perforating jet in a geological formation surrounding the wellbore casing; and
depositing the erosion resistant material within the second hole.Join the waitlist — get patent alerts
