Abstract
The utility model relates to a safe electric ignition device which is suitable for non-housing bomb high energy gas fracture in the oil field. An energy transformation powder column, a safe detonator, a supporting shim, a sealed plastic plug and a compacting shim are arranged in a hole of a base body from the top down. A buffer substrate tablet is arranged between the lower end of the base body and a conversion joint. A hole is arranged in the buffer substrate tablet. The device detonates the safe detonator by a special detonation apparatus. The energy transformation column and the buffer substrate tablet effectively weaken the detonation action, and utilize the high temperature produced by detonation to make the energy transformation powder column burn, and then a reliable combustion is formed by a powder igniting column with the time-delay action. The safe electric ignition device is applicable to the non-housing bomb high energy gas fracture of cable transportation. The safe electric ignition device has advantages of electrostatic resistance, resistance of various stray currents, high safety, reliable ignition, small volume, simple structure, easy manipulation, strong practicability, etc.
Description
(1) technical field:
The utility model relates to a kind of safe electric ignition device; Be applicable to that the oil field do not have the electric ignition of housing bullet high enegry gas fracturing.
(2) background technology:
Existing electric ignition device has two types: a kind of is self-control ignition medicine, light to get angry with the bridge silk and directly light Pressure breaking bullet behind the medicine, its weak point is because static, various stray electrical current around the well site cause mis-ignition, causes accidents such as oil well is scrapped, personnel's injury.Another kind is directly to light Pressure breaking bullet with various electric caps, and its weak point is that igniting is unreliable, detonation wave often occurs and blows Pressure breaking bullet and cause the burning of miso-fire or Pressure breaking bullet insufficient; Existing this electric ignition device of two types has not been suitable for the electric ignition of no housing bullet high enegry gas fracturing.
(3) summary of the invention:
It is reliable that the purpose of this utility model has just provided a kind of antistatic, anti-various stray electrical currents, high safety, igniting, more is applicable to the electrically-fired safe electric ignition device of no housing bullet high enegry gas fracturing.
The purpose of this utility model is achieved in that safe electric ignition device is made up of pedestal, buffer substrate tablet, locking nut, crossover sub, pedestal has endoporus, the aperture is stepped from top to bottom to be reduced successively, the lower end of pedestal is connected with crossover sub, between the lower end of pedestal and crossover sub, be provided with buffer substrate tablet, have the hole on the buffer substrate tablet, power conversion powder column, safety detonator, elastic filler, support pad, sealing plug, compacting pad are housed in the hole of pedestal from bottom to up successively, and their external diameter the internal diameter with its corresponding pedestal 3 is identical respectively; Lead on the safety detonator is drawn through elastic filler, support pad, sealing plug, compacting pad; The igniting powder column is contained in the crossover sub.
At least have a circle groove on the outer wall of the lower end of pedestal, be provided with sealing ring in the groove.
Pedestal with crossover sub between fixedly connected with locking nut.
The thickness of buffer substrate tablet is 2-5mm, and the centre has the 1-10 hole, and the aperture is 0.5-1mm.
Ignite safety detonator (static, various stray electrical current can't detonate safety detonator) by the special use instrument that detonates, comprehensive function by power conversion powder column and buffer substrate tablet, the high temperature that effectively weakens detonative action and utilize detonation to produce makes the burning of power conversion powder column, it is insufficient to have avoided detonation wave to blow miso-fire or Pressure breaking bullet burning that Pressure breaking bullet causes, with after there is the ignition charge post of time-lag action to form safety burning reliably.
That the utility model compared with prior art has is antistatic, anti-various stray electrical currents, high safety, igniting is reliable, volume is little, simple in structure, easy to operate, advantage such as applicability is strong.
(4) description of drawings:
Fig. 1 is the enough schematic diagrames of structure knot of the present utility model.
(5) specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, pedestal 3 has endoporus, the aperture is stepped from top to bottom to be reduced successively, the lower end of pedestal 3 is connected with crossover sub 5 one ends, and crossover sub 5 other ends are connected with no housing bullet during use, is provided with buffer substrate tablet 7 between the lower end of pedestal 3 and crossover sub 5, have the hole on the buffer substrate tablet 7, the thickness of buffer substrate tablet 7 is 2-5mm, and the centre has the 1-10 hole, and the aperture is 0.5-1mm.Power conversion powder column 8, safety detonator 9, elastic filler 10, support pad 11, sealing plug 12, compacting pad 13 are housed in the hole of pedestal 3 from bottom to up successively, and their the external diameter internal diameter with its corresponding pedestal 3 respectively is identical, it is not moved in pedestal 3, and the lead on the safety detonator 9 is drawn in elastic filler 10, support pad 11, sealing plug 12, compacting pad 13.Igniting powder column 6 is contained in the crossover sub 5.
At least have a circle groove on the outer wall of the lower end of pedestal 3, be provided with sealing ring 14 in the groove.Pedestal 3 with crossover sub 5 between fixedly connected with locking nut 4.
160 ℃ of the whole heatproofs of the utility model, withstand voltage 50MPa, special use detonate instrument energising after lead 1 detonates safety detonator 9, comprehensive function by power conversion powder column 8 and buffer substrate tablet 7, the high temperature that effectively weakens detonative action and utilize detonation to produce makes 8 burnings of power conversion powder column, with after there is the igniting powder column 6 of time-lag action to form safe and reliable burning.Housing pin 2, support pad 11, compacting pad 13, sealing plug 12 (180 ℃ of heatproofs, withstand voltage 50MPa), elastic filler 10 comprehensive top seal, the insulating effects of rising.160 ℃ of power conversion powder column 8 heatproofs, 160 ℃ of igniting powder column 6 heatproofs, 160 ℃ of safety detonator 9 heatproofs (safety detonator has only the special use instrument that detonates just can detonate).
