Abstract

A testing system for a shaped charge of a perforating gun, the testing system including a housing; a casing assembly located inside the housing; a perforating gun having at least one shaped charge, the perforating gun being located within the casing assembly; a sample material located within the housing, and in direct contact with the casing assembly; a wellbore accumulator in direct contact with the casing assembly and configured to supply a first fluid, at a wellbore pressure, inside the casing assembly; and a formation accumulator in direct contact with the sample material and configured to supply a second fluid, at a formation pressure, on the sample material.

First claim

What is claimed is:

1. A testing system for testing an impact of a shaped charge on a metal plate, the testing system comprising:
a housing;
a perforating gun located within the housing and having a shaped charge;
a concave metal plate located adjacent to the perforating gun and facing the shaped charge; and
a jet arrester block located within the housing and holding the concave metal plate.

2. The testing system of claim 1 , further comprising:
a holder attached to the perforating gun and configured to move the perforating gun relative to the concave metal plate;
a compressor fluidly connected to the housing and configured to control a pressure of a fluid present inside the housing;
a sensor located inside the housing; and
a controller located outside the housing and configured to receive a signal from the sensor.

3. The testing system of claim 2 , wherein the perforating gun forms an annulus with the housing.

4. The testing system of claim 3 , wherein the sensor is disposed within the annulus.

5. The testing system of claim 2 , wherein a gap is disposed between the perforating gun and the concave metal plate.

6. The testing system of claim 5 , wherein the sensor is disposed within the gap.

7. The testing system of claim 5 , wherein the holder is configured to adjust a width of the gap.

8. The testing system of claim 2 , wherein the sensor comprises a pressure sensor.

9. The testing system of claim 2 , wherein the sensor comprises a temperature sensor.
