Abstract
The utility model relates to an integrally combined hole shooter of an oilfield well. Single base powder (4) packaged by an external angle is arranged between every two perforating charges (7), and the position of a perforating gun matched with each perforating charge (7) forms a blind hole (9). Heat produced by the explosion of perforating charges is used for igniting the power without forming deflagration and a destroying instrument and a gun body. The powder is provided with a protection layer which is not exposed in the air so as not to cause hurt to a human body. The gun body does not need a through hole, thus water does not flow into the gun, and other safety accidents do not occur.
Description
(1) technical field:
The utility model relates to perforating oil gas well simultaneously, and the high pressure that utilizes powder burning to produce in perforating gun carries out the integral type composite perforator of gas fracturing to the stratum.
(2) background technology:
At present, oil field employed rifle internal pressure generating means is to adopt a cylinder grain or solid propellant post, and the different angles out of phase of stick or solid propellant post is provided with and plays the hole, cave, the detonating fuse hole of detonating fuse is worn in the centre, and perforating bullet is installed in and plays in the hole, cave.This stick or solid propellant post are difficult to realize that cost of production is higher on manufacturing process, in the on-the-spot underground work process in oil field, need intercept the composite solidpropellant post at the scene, adjust explosive payload, therefore reduced the construction operation operating efficiency, increased on-the-spot hidden danger; The sealing of pressure release through hole is by a round steel sheet on perforating gun, covers one deck rubber above and constitutes the sealing blanking cover, is embedded in that the pressure release through hole realizes sealing.Because oil gas well depth difference, pressure changes greatly, and the round steel sheet is easy to be out of shape, and loses sealing effectiveness, allows water to flow in the perforating gun, causes detonating fuse not ignited or other dangerous accident occurs; When rifle is adorned in the worker-house, adopt gunpowder to expose in air, distribute the people's smell of choking, harmful.Gunpowder utilizes detonating fuse to light, and is serious to the downhole instrument injury.Dress rifle difficulty is very difficult to blind hole.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem of depositing in the background technology, and a kind of integral type composite perforator that utilizes perforating bullet explosion time heat to light gunpowder is provided.
The invention for solving the technical problem can reach by following technical solution: wrapped single-base powder outside being provided with between per two perforating bullets of firing mount, the perforating gun that each perforating bullet is aimed at locates to constitute the region between the heart and the diaphragm hole outward.
In such scheme, outside the perforating gun that each perforating bullet is aimed at, locate to constitute the blind hole of symmetry.
The utility model is compared with background technology has following beneficial effect: gunpowder is that the heat that utilizes the perforating bullet blast to produce is lighted gunpowder, can not form detonation, the infringement instrument and the body of a gun, and the gunpowder matcoveredn does not expose in air, can not produce injury to human body; The rifle body need not through hole, and current can not gone in the rifle, other security incident can not occur.
(4) description of drawings:
Accompanying drawing is this perforator scheme of installation.
(5) specific embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
Shown in accompanying drawing, wrapped single-base powder 4 outside between firing mount 3 per two perforating bullets 7, being provided with, the perforating gun 6 outer places that each perforating bullet 7 is aimed at constitute the region between the heart and the diaphragm hole 9.
In such scheme, the place constitutes the blind hole 9 of symmetry outside the perforating gun 6 that each perforating bullet 7 is aimed at.Rifle head 1 is arranged at perforating gun 6 tops in addition, interior dress detonator 2 by detonating fuse 5 in the shape of a spiral shape be connected with perforating bullet 7, gunpowder 4.The bottom is the gun breech 8 of perforating gun.
Claims (2)
1, a kind of integral type composite perforator that relates to the oil field well, contain perforating gun (6) and interior perforating bullet (7), gunpowder (4), firing mount (3) thereof, it is characterized in that: wrapped single-base powder (4) outside being provided with between per two perforating bullets of firing mount (3) (7), the outer place of the perforating gun (6) that each perforating bullet (7) is aimed at constitutes the region between the heart and the diaphragm hole (9).
2, the described perforator of root claim 1 is characterized in that: the place constitutes the blind hole (9) of symmetry outside the perforating gun (6) that each perforating bullet (7) is aimed at.
