Abstract
The utility model relates to a perforation is passed and is exploded time delay and succeed and explode device. The device is used for oil pipe conveying perforation and is used for monitoring the booster effect of a perforating gun. The device is connected on the upper portion of the first column perforating gun which is put into the well firstly, in a perforating gun barrel string formed after all perforating guns are connected, the last column perforating gun is used as a perforating effect monitoring sound source, the device replaces a tail sound bullet which is specially used for monitoring the underground booster effect of the perforating gun, the perforating effect is detected by the device, and compared with the existing tail sound bullet, the device is high in vibration sound source energy, obvious in monitoring effect, convenient to install and high in cost performance.
Description
Technical field
The utility model relates to a kind of perforating system in oil field perforation technology field, is particularly applied to a kind of perforation propagation of explosion time delay in oil field prospecting, exploitation perforation completion process and continues quick-fried device.
Background technology
Perforation completion is sport technique segment very important in oil field prospecting, exploitation.Perforator quality, percentage of initiation etc. directly affect oil gas well capacity, and the coda bullet vibrations sound source power of existing conventional perforation device is little, need monitor with instrumentation.
Utility model content
For solving Problems existing in background technology, the utility model proposes the time delay of a kind of perforation propagation of explosion and to continue quick-fried device, can improve the sound source power of vibrations, monitoring effect is obvious.
The technical scheme that the utility model adopts is: in shell, two ends seal respectively and are fixed with overhead gage, lower baffle plate up and down, overhead gage fixing input detonating fuse, lower baffle plate is fixing exports detonating fuse, described ignition charge is connected with input detonating fuse, and be connected with time delay rope upper end and coordinate, described time delay rope is wrapped on rope skeleton, and integral installation is lower middle portion in the enclosure, connecting below time delay rope can detonator, and detonator matches with output detonating fuse; Described ignition charge is intercepted by dividing plate, has O type circle to seal, and is fixed by jackscrew; Described time delay rope, adopts two-way time delay, and bottom connects two detonating primers.
The beneficial effects of the utility model are: by input detonating fuse point of ignition gunpowder, time delay rope lighted by ignition charge, detonating primer after long-time time delay, ignite output detonating fuse, detonate most afterbody perforating gun, instead of the coda bullet being specifically designed to monitoring perforator down-hole propagation of explosion effect, compared with coda bullet, the sound source power of vibrations is high, and monitoring effect is obvious.
Accompanying drawing explanation
Fig. 1 is the utility model organigram.
In figure, 1-input detonating fuse, 2-shell, 3-overhead gage, 4-dividing plate, 5-O type circle, 6-ignition charge, 7-jackscrew, 8-time delay rope, 9-rope skeleton, 10-detonator, 11-lower baffle plate, 12-export detonating fuse.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the time delay of a kind of perforation propagation of explosion continues quick-fried device, during use, this device is exported detonating fuse 12 end and is connected with perforation perforator afterbody rifle top, inputs detonating fuse 1 end and is connected with gun breech portion, top, in shell 2, two ends seal respectively and are fixed with overhead gage 3 up and down, lower baffle plate 11, organize upper and lower two ends influent respectively, the fixing input detonating fuse 1 of overhead gage 3, lower baffle plate 11 is fixing exports detonating fuse 12, described ignition charge 6 is connected with input detonating fuse 1, and be connected with time delay rope 8 upper end and coordinate, input detonating fuse 1 is used for point of ignition gunpowder 6, then ignite time delay rope 8, described time delay rope 8 is wrapped on rope skeleton 9, integral installation is lower middle portion in shell 2, connecting below time delay rope 8 can detonator 10, and detonator 10 matches with output detonating fuse 12, when time delay rope 8 all burnt, detonating primer 10 carries out igniting and exports detonating fuse 12 and export detonating fuse 12 and light bottom perforator, complete delayed firing process, described ignition charge 6 is intercepted by dividing plate 4, O type circle 5 is had to seal, prevent from entering liquid, and fixed by jackscrew 7, described time delay rope 8, adopts two-way time delay, and bottom connects two detonating primers 10, as long as one of them ignites, gets final product propagation of explosion to lower prop perforator, under avoiding unidirectional situation, occurs the unexpected situation cannot carrying out propagation of explosion.
