Abstract

An end plate for securing and orienting a charge tube within a downhole-perforating gun. The end plate includes apertures for receiving locating tabs on the end of the charge tube to ensure the end plate is affixed to the charge tube in a specific orientation. The end plate includes an alignment tab that mates with a corresponding alignment groove in the perforating gun barrel for ensuring insertion of the charge tube into the perforating gun barrel in correct orientation to ensure the perforating charges exit through pre-designed scallops in the perforating gun barrel. A series of apertures may be present within the end plate to allow usage with one of a variety of sizes of charge tube. The end plate may include manipulation spaces along the circumference of the end plate to allow the end plate to be properly positioned or retrieved. The end plate may include an attachment system for attachment of an initiating device.

Description

FIELD OF THE INVENTION

[0001] The present invention relates generally to well perforation tools. More particularly, the present invention relates to an end plate for securing a charge tube within the barrel of a perforating gun. More particularly, the present invention relates to an end plate for securing a charge tube within the barrel of a perforating gun having an attachment system for an initiating device. BACKGROUND OF THE INVENTION

[0002] During the production life of an oil or gas well, it often becomes necessary to perforate the well casing and cement liner of the well in order to obtain access to further deposits within the formation. Several technologies have been developed for this purpose, including the use of downhole explosives, which are generally shaped charges placed and targeted to perforate the casing at a specific well depth and in a specific pattern. Generally, a “gun” containing a series of tailored shaped explosive charges, and a firing head are either run on ...
