Abstract

A reloadable, reusable, downhole interlocking gun and perforation system having two interlocking bodies that each include multiple receivers and barrels. The interlocking bodies are configured to interlock together with each other so that a receiver of one of the interlocking bodies is aligned with a corresponding barrel of the other of the interlocking bodies. Each of the receivers is configured to receive a respective projectile for firing out of the barrel that is aligned with the receiver.

Claims (16)

1 . A gun that is reloadable and reusable, the gun comprising two interlocking bodies that each comprise multiple receivers and barrels, the barrels each defining a passage that extends through the interlocking body where the barrel is located, and the passage is open at both ends, wherein the interlocking bodies are configured to interlock together so that one of the receivers of one of the interlocking bodies is aligned with a corresponding one of the barrels of the other of the interlocking bodies when the interlocking bodies are connected together.

2 . The gun as recited in claim 1 , wherein one of the barrels has an internal diameter in a range of 0.500″ to 0.600″.

3 . The gun as recited in claim 1 , wherein a length of the gun from breech to muzzle is in a range of 1.000″ to 7.000″.

4 . The gun as recited in claim 1 , wherein the gun is configured to receive one or more penetrators in respective receivers.

5 . The gun as recited in claim 1 , wherein the receivers are configured to receive penetrators of different respective shapes.

6 . The gun as recited in claim 1 , wherein the receivers are configured to receive penetrators of different respective lengths.

7 . The gun as recited in claim 1 , wherein the gun is configured and operable to project, fire, or propel, penetrators.

8 . The gun as recited in claim 1 , wherein the gun is configured to shoot a projectile that is configured with a sabot.

9 . The gun as recited in claim 1 , wherein the gun comprises a wet system and is operable to self-pressurize without losing electrical power or communication before and/or after firing.

10 . The gun as recited in claim 1 , wherein the gun utilizes smokeless powder as a propellant for a projectile that the gun is configured to receive.

11 . The gun as recited in claim 1 , comprising a propellant chamber sized to hold between 30 grains and 100 grains of smokeless powder, without the use of wadding.

12 . The gun as recited in claim 1 , wherein the two interlocking bodies comprise barrels and receivers that remain operable at peak pressures of 50,000 psi to 150,000 PSI while preserving reusability of the gun.

13 . The gun as recited in claim 1 , wherein the gun is configured and operable to propel penetrators from a barrel interface through one of the receivers and create perforations that are 1.000″ in penetration past a casing outer diameter and up to 10.000″ past the casing outer diameter.

14 . The gun as recited in claim 1 , wherein the gun is configured to centerfire from top down, towards a breech, and in an opposite direction of one of the receivers.

15 . The gun as recited in claim 1 , wherein one of the barrels includes a port located in a terminal portion of the one barrel.

16 . The gun as recited in claim 1 , wherein, in operation, the gun employs a propellant of either pellet form, or consolidated form, and the propellant comprises smokeless powder and/or black powder.
