Abstract
The utility model relates to a module perforation for rifle efflux energization pass and to explode device, including explosive fuse, last detonating primer, efflux energizer, lower detonating primer four bibliographic categories branch. The efflux energizer is installed in module rifle gun breech, and the upper end is continuous with the detonating primer in the module rifle, and the lower extreme links to each other with the screw thread with module rifle gun breech. Produce the metal efflux after the efflux energizer is ignited, ignite the lower detonating primer of installing in the middle of the metal efflux pierces through behind the obstacle in the next stage module rifle head to ignite next stage module perforation rifle. The utility model discloses a gather the detonating mode of ability metal efflux, improved to pass and exploded the reliability, solved and passed the integrity problem that explodes between module perforation rifle, effectively avoid the emergence of the condition of exploding absolutely.
Description
Technical field
The present invention relates to a kind of module perforating gun tip jet energizing explosion propagation device, be applied in the perforating job of oil, natural gas extraction, relate to energy-gathering jetting and to detonate propagation of explosion technology.
Background technology
In the development process of Oil/gas Well, under some special hole condition conditions, perforating job needs to carry out under high negative pressure state of value, and conventional completion technology can not evade the risk in drilling well, completion and gas reservoir recovery process completely.Module perforating gun technology is the perforating job mode adopted in high negative pressure gas reservoir exploitation process.Be be that module rifle is at the bottom of merogenesis lower going-into-well by branched perforating gun series system difference with conventional perforation rifle string, directly docked by adapter implementation module rifle.After detonating, the detonation energy utilizing upper level module rifle to produce ignites next stage module rifle.Certain thickness metal partion (metp) and well liquid is there is between two formwork rifles, and in module rifle docking operation, differ in gap between each module rifle, between traditional perforating gun, detonation wave Propagation mode can not meet the reliability requirement of propagation of explosion between module rifle, reliably can not ignite next stage module rifle.
Summary of the invention
The technical problem solved
In order to avoid the deficiencies in the prior art part, the present invention proposes a kind of module perforating gun tip jet energizing explosion propagation device, tip jet energizing explosion propagation device is installed in module rifle, improve detonation propagation reliability of nonel tube, solve a difficult problem for propagation of explosion energy shortage between rifle in the perforating job of module rifle, effectively prevent the generation of disconnected quick-fried situation.
Technical scheme
A kind of module perforating gun tip jet energizing explosion propagation device, is characterized in that comprising housing 9, explosive 10 and cavity liner 11; Housing 9 is hollow cylindrical structure, and one end is for being provided with externally threaded openend, and the other end is the sealed end being provided with blind hole, and the center of sealed end is provided with propagation of explosion hole, and propagation of explosion hole is provided with metallic spacer; The cavity liner 11 of pyramidal structure is placed in housing 9, and cavity liner top is positioned at the sealed end of housing 9, and coaxial with propagation of explosion hole; Be the gap of a sealing between cavity liner 11 and housing 9, in gap, fill explosive 10.
Beneficial effect
A kind of module perforating gun tip jet energizing explosion propagation device that the present invention proposes, comprises detonating fuse, upper detonating primer, tip jet energizing device, lower detonating primer four part.Tip jet energizing device is arranged in module rifle gun breech, and upper end is connected with the detonating primer in module rifle, and lower end is connected with screw thread with module rifle gun breech.Tip jet energizing device is detonated rear generation metal jet, and metal jet is ignited peace in next stage module rifle rifle head and held detonating primer after penetrating middle obstacle, thus ignites next stage module perforating gun.The mode that the utility model adopts cumulative metal jet to detonate, improves detonation propagation reliability of nonel tube, solves the integrity problem of propagation of explosion between module perforating gun, effectively avoid the generation of disconnected quick-fried situation.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of tip jet energizing device of the present invention
Fig. 2 is the structural representation that tip jet energizing device of the present invention is arranged in module rifle
1-module rifle gun breech, 2-first detonating fuse, 3-detonating primer, 4-tip jet energizing device, 5-gap, detonating primer under 6-, 7-second detonating fuse, 8-module rifle rifle head, 9-housing, 10-explosive, 11-cavity liner.
Detailed description of the invention
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
Tip jet energizing device of the present invention is made up of housing 9, explosive 10, cavity liner 11 3 part.Housing 9 is hollow cylindrical structure, and one end is for being provided with externally threaded openend, and the other end is the sealed end being provided with blind hole, and the center of sealed end is provided with propagation of explosion hole, and propagation of explosion hole is provided with metallic spacer; The cavity liner 11 of pyramidal structure is placed in housing 9, and cavity liner top is positioned at the sealed end of housing 9, and coaxial with propagation of explosion hole; Be the gap of a sealing between cavity liner 11 and housing 9, in gap, fill explosive 10.
Described cavity liner 11 is pyramidal structure, adopts metal dust compacting or metallic plate punching to make, also can adopt metal bar machine-shaping.
During use, tip jet energizing device 4 is arranged in module rifle gun breech 1, and tip jet energizing device 4 upper end connects with detonating primer 3, and lower end is connected with module rifle gun breech 1 by screw thread.Upper level module rifle gun breech 1 gap 5 that have certain distance middle with next stage module rifle rifle head 8, this gap exists with gases at high pressure, water or well liquid form.The each self-forming of upper and lower two formwork perforating gun independently seal cavity.
After module rifle detonates, detonation wave is passed to detonating primer 3 by the first detonating fuse 2, and ignites detonating primer 3.The Detonation Shock Wave that detonating primer 3 detonation produces is through the metallic spacer on top, propagation of explosion hole, tip jet energizing device upper end, explosive 10 is ignited, cavity liner 11 forms metal jet under the promotion of detonation wave, after metal jet penetrates the metal partion (metp) of module rifle gun breech, by well liquid or gas gap and lower detonating primer 6 ignited by the metal partion (metp) penetrating next stage module rifle, the second detonating fuse 7 ignited again by lower detonating primer 6, ignites subordinate's module rifle successively.
