Abstract
Provided is a backpressure type eccentric bullet-fixing rack for a perforating bullet, which belongs to the bullet-fixing field of perforating bullets of oil and gas well perforation, and comprises a bullet rack composed by a seamless steel pipe or a welding steel pipe. The tube wall of the bullet rack is provided with positioning holes for mounting perforating bullets, a positioning boss, a backpressure type bullet-pressing edge and a detonating cord and a guide groove. The detonating cord winds around the guide groove along the bullet rack in the shape of spiral line, and the perforating bullet deviates the axis of the bullet rack based on a phase and is fixed. The fixing position of the backpressure type perforating bullet deviates the center line of a perforating gun. With scientific and reasonable structure, simple producing process, and convenient and strong operation, the backpressure type eccentric bullet-fixing rack can enhance the firmness of perforating bullets on the perforating gun, achieve eccentric fixing of perforating bullets, increase the piercing depth of the perforator, and fix perforating bullets.
Description
Technical field
The utility model provides a kind of perforating bullet off-centre that is used for perforating oil gas well to play mode admittedly, pressure type off-centre firing mount admittedly behind especially a kind of perforating bullet.
Background technology
At present, be used for perforating oil gas well lined-cavity charge fixedly be to withstand in the circular pipe type firing mount hole by the body male cone (strobilus masculinus), the perforating bullet other end compresses with firing mount; In perhaps perforating bullet was packed circular pipe type firing mount hole into, the perforating bullet other end compressed with detonating fuse.Because the height of perforating bullet is limited, it is in the middle position substantially in perforating gun, and the interior space of perforating gun can not be made full use of, and wearing deeply of perforating bullet can not be given full play to.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: a kind of space in the perforating gun that makes full use of is provided, improve the perforating bullet height of burst, and make the perforating bullet fixation, give full play to the dark performance of wearing of perforating bullet, reach and improve perforator and wear behind the perforating bullet of dark purpose pressure type off-centre firing mount admittedly.
The technical scheme that its technical problem that solves the utility model adopts is: pressure type off-centre plays firing mount admittedly behind a kind of perforating bullet, comprise the firing mount that seamless steel pipe or welded steel pipe are made, it is characterized in that: the tube wall of described firing mount is provided with circular perforating bullet and shoots locating hole, positioning boss, back pressure type pressure bullet seamed edge and detonating fuse gathering sill, detonating fuse along firing mount in the shape of a spiral line detour along the detonating fuse gathering sill, perforating bullet is fixed by phase deviation firing mount axis.
Perforating bullet adopts the back pressure type to be fixed in the firing mount by phase deviation firing mount axis, makes the perforating bullet permanent position depart from the center line of perforating gun, improves the fastness of perforating bullet on perforator, and is convenient, workable when perforating bullet uses.The phase angle size can be provided with as required, makes to arrange on firing mount in order, saves the space, increases operation rate.
Wherein preferred version is:
Described firing mount outer wall is provided with the back pressure type and press plays seamed edge, and pressure type is pressed and played that seamed edge is corresponding to be provided with after two.Be convenient to fix.
Two positioning boss of mutual correspondence are set in the described perforating bullet locating hole.Both corresponding setting, the installation effectiveness of raising detonating fuse.
Press bullet seamed edge and firing mount center line to be 40 ° of-60 ° of angles for described two.The convenient installation.
The pressure type off-centre beneficial effect that firing mount had admittedly is behind the utility model perforating bullet: the tube wall by firing mount is provided with circular perforating bullet and shoots locating hole, positioning boss, back pressure type and press and play seamed edge and detonating fuse gathering sill, detonating fuse along firing mount in the shape of a spiral line detour along the detonating fuse gathering sill, perforating bullet is fixed by phase deviation firing mount axis, make the perforating bullet permanent position depart from the center line of perforating gun, improve the fastness of perforating bullet on perforator, convenient, workable when perforating bullet uses.The phase angle size can be provided with as required, makes to arrange on firing mount in order, saves the space, increases operation rate.Can realize: improve the fastness of perforating bullet on perforator, realize that perforating bullet is eccentric fixing, improve perforator and wear deeply, fixing perforating bullet scientific structure, rationally, manufacturing process is simple, easy goes.It is convenient, workable when perforating bullet uses.

Wherein: 1, detonating fuse gathering sill 2, pressure play seamed edge 3, shoot locating hole 4, firing mount 5, positioning boss 6, pad 7, detonating fuse groove 8, cone 9, cylinder 10, detonating fuse 11, firing mount body 12, perforating gun.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Embodiment 1:
As shown in Figure 1 and Figure 2, the firing mount 4 that seamless steel pipe or welded steel pipe are made, its tube wall is provided with circular perforating bullet and shoots locating hole 3, positioning boss 5, back pressure type pressure bullet seamed edge 2 and detonating fuse gathering sill 1, detonating fuse 10 along firing mount in the shape of a spiral line detour along detonating fuse gathering sill 1, perforating bullet is fixed by phase deviation firing mount 4 axis.
Shooting locating hole 3 as shown in Figure 4 has two positioning boss 5, is used for fixing the radial position of perforating bullet, by regulating the position of two positioning boss 5, makes the center line of perforating bullet misalignment firing mount body 11, perforating gun 12.Shooting on locating hole 3 both sides and 40 °～60 ° directions of steel pipe firing mount 4 axis, opening two and press bullet seamed edge 2, be used to compress perforating bullet.
The angle of gathering sill 1 gathering sill and firing mount body 11 axis is a helical angle, the close and firing mount caliber adjustment angle according to the hole.
Be illustrated in figure 3 as the perforating bullet profile, perforating bullet one end is a cylinder 9, shoots locating hole 3 with firing mount and cooperates, be used for fixing perforating bullet, the other end is a cone 8, stirs two pressures that shoot on the locating hole 3 from behind round about and plays seamed edge 2 and compress perforating bullet, makes the perforating bullet fixation.
Original perforating bullet, firing mount 4 and perforating gun 12 are common prior art in the utility model, its setting and use to industry technician and grasped.
Operating principle and use:
Article two, press the angle that plays seamed edge 2 and firing mount 4 axis to adjust angle according to perforating bullet profile and firing mount 4 calibers.Perforating bullet is packed into from shooting locating hole 3, positioning boss 5 and locating hole with perforating bullet radially, axial location fixes, wire-wound is capable in the shape of a spiral along firing mount 4 external surfaces for detonating fuse 10, is pressed on the perforating bullet detonating fuse groove 7, pad 6 compresses detonating fuse, presses bullet seamed edge 2 to compress perforating bullet cone 8 from behind for two.
