Abstract
A metal powder linear perforating charge consists of a perforating charge casing and a high-density grain, and is characterized in that a linear utilizes a metal powder linear, and the cross section of the linear is in the shape of a parabolic line. The parabolic metal powder linear is formed by pressing a mixture consisting of copper powder, bismuth meal, aluminum powder, rubber binder and the like on a special die. Depth of concrete target punching hole is increased by over 35% compared with the existing copper plate linear large-aperture perforating charge, and punching aperture on the sleeve is slightly larger than that of the copper plate linear large-aperture perforating charge. The metal powder liner perforating charge is reasonable and simple in structure, low in cost, fine in using effect and wide in application range and has popularization value.
Description
Technical field
The utility model relates to the improvement of the perforating bullet that uses in oil exploration and the mining operations, is a kind of powdered metal liner perforating bullet specifically.
Background technology
In oil exploration and mining operations, need to use perforating bullet that the down-hole petroliferous bed is carried out perforating job, in the sand control oil producing operation, need on wellbore casing, open the bigger profit passage in aperture, the cavity liner of existing large aperture perforating bullet is mostly made by the copper coin material, is not easy to improve the concrete target penetration depth of perforating bullet and the piercing aperture on the sleeve pipe again.
The utility model content
The purpose of this utility model is at above-mentioned deficiency, provides a kind of simple in structure, can improve the concrete target penetration depth of perforating bullet and the powdered metal liner perforating bullet of the piercing aperture on the sleeve pipe.
The technical scheme that realizes the utility model purpose is:
This powdered metal liner perforating bullet is made of perforating bullet housing, high density powder column, is characterized in that cavity liner is a powdered metal liner, and the cross sectional shape of cavity liner is parabola shaped.
This powdered metal liner that is parabolic shape, the mixture that can be made up of materials such as copper powder, bismuth meal, aluminium powder and rubber cements suppresses forming on particular manufacturing craft.
This powdered metal liner perforating bullet will improve more than 35% than the concrete target penetration depth of existing copper coin cavity liner large aperture perforating bullet, the piercing aperture of the piercing aperture on the sleeve pipe a little less than a little more than copper coin cavity liner large aperture perforation.Have simple and reasonable, advantages such as cost is low, result of use good, applied range, have promotional value.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Among the figure: 1 perforating bullet housing, 2 high density powder columns, 3 powdered metal liners.
The specific embodiment
The utility model is further described with the embodiment that provides below in conjunction with accompanying drawing.
With reference to accompanying drawing, this powdered metal liner perforating bullet is made of perforating bullet housing 1, high density powder column 2, and characteristics are that cavity liner is a powdered metal liner 3, and the cross sectional shape of cavity liner is parabola shaped.
The utility model is simple in structure, implements easily.The applicant presses embodiment, after selecting for use 65% copper powder, 20% bismuth meal, 15% aluminium powder and rubber cement to mix, on particular manufacturing craft, be pressed into powdered metal liner, on forcing press, perforating bullet housing, high density powder column and the compacting of parabola shaped powdered metal liner are fixed as one again, make the powdered metal liner perforating bullet.The on probation demonstration through inside, simple and reasonable, cost is low, result of use good, applied range, is subjected to trier's favorable comment.
