Benefits of technology

The patent text describes a method for making a shaped charge by adding explosive material to a case, adding a liner over the explosive material, and installing a retainer ring to hold the components in place. This method helps to prevent the liner and explosive material from moving in the shaped charge case. The technical effect of this method is to improve the accuracy and reliability of shaped charges used in industrial applications.

Problems solved by technology

Adhesives present issues during the manufacturing process that incur additional costs and have environmental issues.

Embodiment Construction

[0022]In the following description, certain terms have been used for brevity, clarity, and examples. No unnecessary limitations are to be implied therefrom and such terms are used for descriptive purposes only and are intended to be broadly construed. The different apparatus, systems and method steps described herein may be used alone or in combination with other apparatus, systems and method steps. It is to be expected that various equivalents, alternatives, and modifications are possible within the scope of the appended claims.

[0023]Referring to FIG. 1, a typical perforating gun 10 includes a gun body 11 that houses the shaped charges 12. The gun body 11 contains end fittings 16 and 20 which secures the charge tube 18 into place. The charge tube 18 has charge holes 23 that are openings where shaped charges 12 may be placed. The gun body 11 has threaded ends 14 that allow it to be connected to a series of perforating guns 10 or to other downhole equipment depending on the job requi...

Abstract

A shaped charge retainer ring for use in containing the liner of a shaped charge and the explosive material.

Description

RELATED APPLICATIONS[0001]This application is a U.S. divisional application of U.S. Nonprovisional patent application Ser. No. 15 / 563,816 filed Oct. 3, 2017, which is a 371 of International Application No. PCT / US16 / 25725 filed Apr. 1, 2016, which claims priority to U.S. Provisional Application No. 62 / 142,099, filed Apr. 2, 2015.BACKGROUND OF THE INVENTION[0002]Generally, when completing a subterranean well for the production of fluids, minerals, or gases from underground reservoirs, several types of tubulars are placed downhole as part of the drilling, exploration, and completions process. These tubulars can include casing, tubing, pipes, liners, and devices conveyed downhole by tubulars of various types. Each well is unique, so combinations of different tubulars may be lowered into a well for a multitude of purposes.[0003]A subsurface or subterranean well transits one or more formations. The formation is a body of rock or strata that contains one or more compositions. The formation...
