Definitions
- the invention relates to a perforation cannon according to the preambles of claims 1 and 3.
- Perforation guns are used in deep well blasting in the oil and gas industry to connect the well to the storage horizon.
- a perforation cannon consists of an outer cannon tube, inside of which perforators - usually hollow or gusset charges - are arranged, which when fired shoot radially outwards through the cannon tube. Bullet holes remain in the gun barrel after the shot.
- a detonating cord leads to the ignition of the perforators through the cannon tube, which causes the perforators to ignite when ignited.
- the invention is based, to improve a perforation cannon according to the preamble of claim 1 so that with simple and safe the task
- BESTATIGUNGSKOPIE Averaging of fragments from the gun barrel into the bore is avoided.
- this object is achieved in a first embodiment in that the means for the automatic closure comprise cartridges with a swellable 2-component foam and these cartridges are arranged in the gun barrel and can be broken open by the detonated detonating cord, causing foam to escape from the cartridges and plugged the bullet holes.
- a cartridge is arranged adjacent to a perforator.
- Perforation cannons with an outer cannon tube, in the interior of which perforators are arranged, which can be ignited via an explosive cord leading through the cannon tube and, after ignition, penetrate the cannon tube at the bullet holes, means for automatically closing the bullet holes being provided and these means comprising a sliding tube, which can be displaced by at least the diameter of the bullet hole after being shot through an adjusting device, it is proposed that the sliding tube be arranged coaxially between the perforators and the gun barrel. This prevents fragments from escaping from the gun barrel into the bore with simple and safe means. In the case of horizontal bores where the outer wall rests on the casing inner wall, it is possible to move the sliding tube safely.
- the sliding tube is fixed in its starting position by means of a securing element which breaks open after the detonating cord has been ignited and releases the displacement of the sliding tube.
- the adjusting device can be a tensioned spring or a pyrotechnic element that can be ignited by the detonating cord.
- the sliding tube is closed on the side into which it is to be displaced and is open on the other side, as a result of which the sliding tube is designed like a piston which can be displaced by the pressure which builds up as a result of the ignition of the perforators.
- the sliding tube have a wall thickness which allows radial expansion due to the pressure built up in the gun barrel after the perforators have been ignited.
- a fluid is advantageously arranged between the slide tube and the gun barrel.
- the timing of the radial expansion of the sliding tube can be controlled with this fluid.
- FIG. 1 shows a cannon tube 1 of a perforation cannon for use in the petroleum and natural gas industry for connecting a bore to the storage horizon.
- the gun barrel 1 is closed at both ends by a connector or closure 18.
- a sliding tube 4 In the interior of the gun barrel 1 there is a sliding tube 4 and therein a load carrier 9 to which perforators 10 are fastened.
- these perforators are 10 shaped charges.
- an explosive cord 11 is guided to the respective ignition points of the perforators 10.
- the detonating cord 11 is guided through the connectors or terminations 18 into the interior of the perforation gun.
- the inner tube or the sliding tube 4 is z. B. closed by a cap 5.
- predetermined breaking points 3 can be introduced, so that after the perforators 10 have been ignited, the shaped charge jet 12 (see FIG. 2) which is formed can penetrate the gun barrel 1 unhindered.
- Fig. 2 shows a section of the perforation gun immediately after ignition.
- the detonating cord 11 has ignited the perforators 10.
- the shaped charge jet or shaped charge jet 12 which has formed has penetrated the sliding tube 4 and the gun barrel 1.
- the metal housings of the perforators 10 disassemble and form fragments and fragments that form part of the “debris”.
- Figure 3 shows a section of the perforation gun immediately after the shot.
- the shaped charge jet 12 has penetrated the sliding tube 4 at the shot hole 14 and the cannon tube 1 at the shot hole 13.
- a pressure has built up inside the sliding tube 4. This pressure acts on the sliding tube 4 in the direction of the securing element 7, since the sliding tube 4 is closed on the side of the securing element 5 by a cap 5 and is open on the opposite side.
- "Debris" 17 has formed inside.
- Figure 4 shows a section of the perforation gun after the shot.
- the securing element 7 has been sheared off by the pressure in the sliding tube 4, as a result of which the sliding tube 4 has shifted up to the nearby connector or closure 18.
- the remaining small parts or the debris 17 cannot leave the gun barrel 1. It is not shown that this is Inner tube 4 inflated after the shot and thus wedged with the gun barrel 1.
- the invention thus consists of a mechanism which closes the perforation holes or bullet holes 13 in the cannon wall 2 after the shot and thus prevents the "debris" 17 from escaping.
- Foam cartridges or, as described, a slide or rotation mechanism can serve as the locking mechanism
- some perforators 10 are replaced by cartridges with 2-component foam, and the detonating cord 11, which ignites the perforators or charges 10, causes the cartridge to react, the foam swells and clogs the bullet holes 13.
- a second tube, a sliding tube 4 is inserted into the cannon, which after being shot through is displaced by at least the diameter of the shot hole 13 (either longitudinally; sliding mechanism or transversely, rotating mechanism).
- the displacement path is identified by an X (see reference numeral 8).
- a preloaded spring can be used to move the inner tube or second tube or sliding tube 4 after the shot.
- the sliding tube 4 is fixed in the starting position via a securing element 7 which, for. B. is destroyed by the detonating cord 11.
- a securing element 7 z. B. bolts, snap rings or screws. The destruction can e.g. B. also via a pyro-technical element - possibly also with a delay block.
- the internal pressure in the cannon after the shot caused by the reaction products of the explosives in the perforators 10 can also serve to move the slide mechanism or the slide tube 5. If the sliding tube 4 is closed on the side into which it is to move and kept open on the other side, this sliding tube 4 can move like a piston. The internal pressure can only be relieved through the perforation holes 14 and the bushings 6 for the detonating cord 11. The time to complete pressure reduction is sufficient to move the slide tube 4 and thus to close the bullet holes 13, 14. At the same time, the gas pressure causes the slide tube 4 to inflate (also known for conventional perforation guns under the term “gun swell”). The expanding slide tube 4 can wedge against the inner wall of the outer tube or gun tube 1 and therefore cannot slip back Expansion can be controlled, for example, by means of a fluid between the inner and outer walls, for example using grease or silicone oil.
