Definitions
- Figure 3 is a side elevation of an embodiment of the invention utilizing external ribs containing the explosive charges;
- Figure 4 is a side elevation of an embodiment of the invention utilizing an explosive linear strip;
- the self-perforating tubing or casing of the present invention is made from standard tubular materials having coaxial outside and inside surfaces with a closed wall extending therebetween. At least one explosive charge is mounted in direct contact with the outside surface of the wall of the tubular. This contact may be a mechanical connection, such as, by adhering the explosive charges to the outside surface of the tubular; but preferably is by drilling receiving blind bores in the wall of the tubular and fixing the explosive charges into the respective blind bores; or by bracketing, banding, clamping or by the use of adhesives the explosive charges to the outside surface of the tubular.
- the tubular itself may also be modified in other ways to carry the explosive charges.
- the present method can be ' 5 considered “plugging" in that an explosive charge is set in contact with the casing wall, or in a partially penetrating blind bore drilled into the casing wall, and detonation of that explosive charge creates a stress riser that shears a steel "plug" out of the casing wall 0 leave a hole of known geometry and size without burrs or splatter inside the casing that can block or damage equipment being run in the hole.
