Definitions
- the invention relates to a method for transmitting the detonation effect of one detonating cord to the other according to the preamble of claim 1 and an apparatus according to the preamble of claim 3.
- Perforation systems as an example in which secure transmission of the detonation effect is extremely important, e.g. B. used in deep borehole blasting in the oil and gas industry to connect the hole to the storage horizon.
- a perforation system consists, as required, of a plurality of individual segments with perforators, each segment consisting of a carrier tube with an internal holding device for receiving the perforators.
- the individual segments are often connected only at the place of use via connecting parts with each other in the axial direction.
- the perforators are ignited by detonating cords. Since the individual segments are connected only at the site, it is known to connect the detonating cords so that the ignition is transmitted from one segment to another.
- the detonating cords are provided at their ends with boosters (ignition stages, amplifiers), wherein the first booster of the detonating cord of the first segment with the adjacent second booster of the detonating cord of the second element is coupled so that the two booster in their axial direction are opposite, d , H. arranged on a straight line opposite each other.
- Boosters are generally understood to mean a donor or acceptor booster. Coupled is the donor booster of one detonating cord with the acceptor booster of the other detonating cord or vice versa. Under booster, however, is also understood a bidirectional booster. For simplicity's sake, therefore, this description will only speak generally of boosters without going into the distinction between donor boosters and acceptor boosters or bidirectional boosters.
- the above-mentioned connecting part is screwed with its one thread into a segment. Subsequently, the detonating cord, provided with a booster, is inserted into the connecting part and the segment such that the booster is in the region of the end of the connecting part facing the adjacent segment.
- the disadvantage here is that can vary by temperature influences the distance between the end faces of two adjacent booster, whereby a secure transmission of the ignition is often not guaranteed.
- the length of the detonating cord must be adjusted exactly to the measured length.
- foreign objects may accumulate between the faces of the boosters, which can interfere with the transfer of the ignition and also ensure that the adjacent booster is not initiated.
- transfer kits require many items and are therefore expensive and labor intensive. Due to varying outer diameter of the charge carrier tube different transfer kits are needed.
- the invention has for its object to improve a method for transmitting the detonation effect of one detonating cord to the other according to the preamble of claim 1 so that the transmission is guaranteed even in difficult conditions and few items are needed.
- this object is solved by the features of claim 1. Characterized in that at least one booster of two adjacent detonating cords to the other booster is subjected to force, so that the front sides of the Touch adjacent booster always, the transmission is ensured by simple means, even in difficult installation conditions.
- the boosters are arranged in receiving devices and at least one of the receiving devices of two adjacent detonating cords is subjected to a force to the adjacent receiving device.
- At least one of the receiving devices is subjected to force in the direction of the adjacent receiving device, so that the front sides of the adjacent booster always touch each other when the device is used.
- the non-force-loaded receiving device is preferably fixed in the segment. - A -

- the device is a Perforationskanone for Tiefbohrlochsprengun- gene and the charges are perforators.
- the force is applied to the other receiving device via a spring.
- a spring is applied to the other receiving device via a spring.
- other types of force application are possible.
- the receiving devices are made of temperature-resistant (up to 260 ° C) half-shells in which the booster and a part of the adjacent detonating cord are fixedly inserted.
- the half shells are made of plastic, preferably sprayed.
- the plastic is preferably one of the following:
- PAGT High Temperature Polyamide
- PFA Perfluoroalkyl Vinyl Ether
- PEEK Polyether Ether Ketone
- FEP Hexafluoropropylene
- Another feature of the invention is characterized in that the kraftbeaufschlagte other receiving device is inserted via a bayonet closure against the force of the spring axially biased in an end plate of the associated segment.
- the bias is thus effected here by a spring, the force applied to the other receiving device in the direction of the adjacent receiving device of the adjacent segment.
- the bias can also be applied by another device.
- the other receiving device is automatically subjected to a force against the spring.
- Both recording devices can also be subjected to force against each other.
- the half-shells of the receiving devices on clamping pins and recesses, which are interchanged or mirrored between the two half-shells of a receiving device. As a result, only matching half shells are assembled.
- a recess advantageously a bore is arranged in the connecting part, into which a receiving device is pushed up to a stop and the adjacent other receiving device of the adjacent segment protrudes into this recess, wherein the end faces belonging to the two receiving devices booster in the Be stored. This protects the front area of the booster from contamination.
- the end faces of the receiving devices are mushroom-shaped in section, so that contaminants are displaced during assembly or do not deposit on the end faces.
- the other receiving device pushed into the indentation up to a stop has an O-ring on its peripheral surface, which bears against the wall of the indentation.
- electrical contacts are arranged on the receiving devices, which touch each other after application of force to the receiving device and, in addition to the transmission of the detonation effect, an electrical connection of the contacts thus takes place.
- a control signal for electrical or electronic components is preferably transmitted via the contacts and the control signal is an ignition signal to a detonator.
- FIG. 10 shows a section of a perforation system, which consists of a series arrangement or mutual coupling of individual segments 19, 20.
- Such perforation systems are u. a. used for penetration of boreholes.
- each of these segments 19, 20 consists of a carrier tube 9 and a charge carrier tube 8 arranged in the carrier tube 9.
- Perforators 14 are attached to this charge carrier tube 8. In this case, it is Hollow perforators that break through the support tube 9 when it ignites and break up or penetrate the borehole wall, not shown here.
- the individual segments 19, 20 are rigidly connected to each other via a connecting part 11.
- the connecting part 11 has at its two ends in each case a thread on its outer circumference, with which the connecting part 11 is screwed into the segments 19, 20 or in the carrier tube 9 thereof.
- a detonating cord 5 is guided through the individual segments 19, 20, which grazes the perforators 14 on its rear side and causes it to ignite when ignited.
- the invention described herein improves the transfer of ignition from one segment 19 to the other segment 20.
- Figures 1 to 4 show an enlarged detail of Figures 9 and 10 in another illustration.
- the ignition is transferred via a booster kit DW (transfer system), which in the embodiment described here consists, inter alia, of two half shells 1, 2 made of molded plastic, which form the associated receiving device 22.
- DW transfer system
- a booster 4 is choked and inserted into one of the two half-shells 1, 2, wherein the end face of the booster 4 almost flush with the end face of the receiving device 22 (see Figure 9) or the two half-shells 1, 2 closes.
- the front side of the receiving devices 21, 22 is mushroom-shaped 28, so that during assembly contaminants are displaced, or do not deposit on the end faces.
- the two half-shells 1, 2 can be plugged together, they have clamping pins 6 and recesses 13, whose positions between the two half-shells 1, 2 are arranged reversed, the clamping pins 6 fit a half-shell in the recesses 13 of the other half-shell and vice versa ,
- a spring 3 is pushed in the form of a spiral spring on the detonating cord 5.
- the two half-shells 23, 24 can also be screwed together.
- the two half-shells 23, 24 can be dismantled, a preferably wedge-shaped opening 29 is attached to the connecting edge. With commonly used tools, such as a screwdriver, then the two half-shells 23, 24 can be easily separated.
- openings 17 are introduced, through which the end face of the receiving device 22 opposite to the force of the spring 3 can push so positioned that it locks by a subsequent 90 degrees rotation and forms a bayonet closure ,
- Figure 2 shows the Eindschreibvorgang. With the arrow 25, the Eindschreiblatin is designated.
- the receiving device 22 is pushed maximum. The spring 3 is compressed. Now the receiving device 22 is rotated by 90 degrees and released again.
- the pickup device 22 is biased in the end plate 7 (see FIG. 4).
- Figures 5 to 8 show the introduction of the receiving device 21 in the connecting part 11.
- the detonating cord 5 is passed through the segment 20 of a perforator 14 to the other and also extends through the connecting part 11. Good to see the thread 26, with which the connecting part 11 is screwed into the segment 20.
- a booster 4 is angegeschgt or attached to the detonating cord 5 and inserted into one of the two half-shells 23, 24 and fixed by compressing the half-shells. Again, the end face 15 of the booster 4 is flush with the end face of the two half-shells 23, 24 and the receiving device 21 (see also Figures 9 and 10).
- an O-ring 12 (see FIG. 6) is inserted on the outer circumference of the receiving device 21 in a circumferential groove 27 provided for this purpose.
- the receiving device 21 is inserted into an indentation 10, such that the receiving device 21 rests on a stop 18 (or paragraph). Even when pressure is applied to the receiving device 21, it can not be pressed further than to this stop 18 (see FIGS. 7 and 8 and FIGS. 9 and 10).
- the receiving device 22 When fastening the connecting part 11 with the segment 19 (see FIG. 9), the receiving device 22 protrudes into the indentation 10 in the connecting part 11 until the two receiving devices 21, 22 and thus the booster 4 contact each other at their end faces. Subsequently, upon further screwing of the connecting part 11 in the segment 19, the receiving device 21 exerts a pressure on the receiving device 22 and pushes it against the force of the spring 3 in the direction of the end plate 7. As a result, both receiving devices 21, 22 with pressure to each other ge - presses and thus also the faces of the booster 4.
- the described booster kit DW according to the invention thus consists of four temperature-resistant (preferably up to 260 0 C) and, for example, sprayed half shells 1, 2 made of plastic and a standard metal spring. 3
- the additional part of the booster kit DW is the profile 17 in the lower part of the end plate 7 of the charge carrier tube 8, which allows for easy installation of the two clamped half shells 1, 2 by means of a positioned rearward recess and a subsequent 90 ° rotation.

- the spring 3 In addition to the fixation of the booster kit in the end plate 7, the spring 3 also provides flexibility. With the different diameters and the different distances between the individual booster kits, which are located in the respective carrier tubes 9 of the connecting parts 11, a dynamic tension is built up, which prevents foreign bodies from accumulating between the booster devices. The assembled parts can easily be taken apart with a simple tool, if necessary. The explosive components can thus be recovered undamaged in case of too high aging (after 5 years) or after cancellation of the use of the carrier tubes.
- the explosive components (detonating cord 5, booster 4) in the booster kit / transfer / kit are held on the receiving device 22 by means of preformed profiles 16 or clamped in the end plate 7.
- the receiving device 22 is fixed.
- the Booster Kit / Tansfer Kit can be easily disassembled and reused multiple times should it not be for use with explosives.
- the invention is thus characterized by the fact that the respective ends of the detonating cord 5, on which the booster 4 are located, are inserted immovably into two half-shells 1, 2, 23, 24 of preferably plastic. These two half shells 1, 2, 23, 24 with the end of the detonating cord 5 and the booster 4 are then inserted into the connecting part 11 and into the end plate 7 of the adjacent support tube 9. Very important here is that one of these two parts, consisting of two half-shells, in the direction of the other adjacent Part force is applied, so that between the two faces of the two booster 4 no gap is present. This force is preferably applied by the spring.
