摘要： A method of producing a liner (5) for a shaped charge (1) comprising mixing a composition mixing a composition of powdered metal with plasticizers and binders to form a paste. The paste is then particulated and injected into an injection mold. The paste is molded into a molded liner shape (5) and then chemically treated to remove plasticizers and binders from the molded liner shape. After being removed from the injection mold the molded liner shape is sintered inside of a furnace. The powdered metal composition can be comprised of a mixture of from 60 % to 97 % by weight of powdered heavy metal and from 40 % to 3 % by weight of cobalt, or the powdered metal composition can be comprised of a mixture of from 60 % to 97 % by weight of powdered heavy metal and from 40 % to 3 % of copper, the preferred heavy metal being tungsten.

摘要： A liner for a shaped charge formed from a mixture of powdered heavy metal and a powdered metal binder. The liner is formed by compression of the mixture into a liner body. In one embodiment of the invention, the mixture comprises a range of 50 to 93 percent by weight of tungsten, and 50 to 7 percent by weight of the powdered metal binder. In a specific embodiment of the invention, graphite powder is intermixed with the powdered metal binder to act as a lubricant during formation of the shaped charge liner. The powdered metal binder can be a combination of copper powder, lead, and molybdenum.

摘要： Disclosed herein is a reinforcing system for a shaped charge assembly for use in a perforating gun. The shaped charge assembly includes a shaped charge combined with a longitudinal reinforcing system extending along a portion of a perforating gun barrel. The reinforcing system comprises a spine with a recess formed to receive the shaped charge of a perforating gun. The reinforcing system further comprises a compression zone coaxially disposed around a portion of the shaped charge. The compression zone is formed between a bushing and a retaining shell that also coaxially circumscribe a portion of the shaped charge and on one of their respective ends connect to the spine.

摘要： Disclosed herein is a locator system for a cutting device in combination with a production string. Where the production string has at least one detent along its circumference. The invention also comprises a lock formed to engage the detent, a cutting device, and a body on which the lock is attached. The body is connected to the cutting device such that when the lock is engaged to the detent, the cutting device is operatively connected to the detent and the cutting device is positioned at a location to accurately sever the production string at a desired depth. An alternative embodiment of the detent is a nipple profile and the production string comprises a series of tubing members connected end to end. The tubing members can be a completion tool, tubing, or a combination of both. Also disclosed is a method of using the locator system.
