The specific embodiment
The organization plan and the course of work below in conjunction with instance explanation the utility model.
As shown in Figure 1; A kind of oil well perforation is ignited with the time-delay electric initiator, comprises cover 16 in lead 1, rubber cap 2, nut 3, right felt pad 4, central electrode 5, interior cover 6, insulating sleeve 7, contactor housing 8, O RunddichtringO 9, sealing ring 10, left felt pad 11, switch spring 12, butt joint housing 13, electrode cap 14, short-circuit spring 15, the insulation, holder 17, electric match 18, time-delay blasting cap 19.
The lead 1 of the utility model is fixing by rubber cap 2, and is connected with central electrode 5 welderings, and on the cover 6, interior cover 6 was provided with O RunddichtringO 9, and is contained in the contactor housing 8, between interior cover 6 and the contactor housing 8 switch spring 12 is housed in rubber cap 2 was fixed on.The endoporus of interior cover 6 is provided with insulating sleeve 7, is provided with central electrode 5 in the insulating sleeve 7, and its two ends are respectively arranged with left felt pad 11 and right felt pad 4, and is fixed on the interior cover 6 through nut 3, and nut 3 is arranged on the central electrode 5.Contactor housing 8 is provided with sealing ring 10, and contactor housing 8 is fixed on the butt joint housing 13, is provided with cover 16 in the insulation in the hole of butt joint housing 13, and is fixed on the butt joint housing 13 through holder 17.Be provided with short-circuit spring 15 between electrode cap 14 and the electric match 18, and be arranged in the hole of the interior cover 16 of insulation, overlap in 16 in electric match 18 is arranged on holder 17 and insulate, and fix through time-delay blasting cap 19, time-delay blasting cap 19 is fixed on the holder 17.Time-delay blasting cap 19 is the serial blasting cap of uniformly-spaced delaying; Be divided into 5 uniformly-spaced delay numbers; Promptly the 1st section be 0ms, the 2nd section for 1500ms, the 3rd section for 3000ms, the 4th section are 6000ms for 4500ms, the 5th section, also can in 0ms～6000ms, adjust uniformly-spaced defer time as requested arbitrarily.19 with medicament of time-delay blasting cap are the heatproof medicament, and the heatproof technical indicator is 160 ℃, 48h.
The course of work of this time-delay electric initiator is: time-delay electric initiator and perforating gun rifle head fit together, and are transported to the down-hole through oil pipe, arrive certain oil well depth after; Under the fluid pressure effect in oil well; The interior cover 6 compression switch springs 4 that are provided with central electrode 5 move downward, and the front end of central electrode 5 promotes electrode cap 14 compression short-circuit springs 15 and moves down, and electrode cap 14 is thrown off with butt joint housing 13; Because shell body is a negative pole; Electric match 18, central electrode 5 are anodal, thus the releasing of the short circuit shape of electric match 18, and pass through short-circuit spring 15 and connect with the electrode cap 14 and the positive pole of central electrode 5; After perforating gun arrived the appointment oil reservoir, the cable energized was detonated the time-delay electric initiator.If the employing oil tube conveying gun perforation is then cast power bar at well head, when power bar makes after dock the electric initiator of delaying time detonate in the down-hole with the time-delay electric initiator.If oil pipe is carried multiple zone perforation simultaneously; A defer time different time delay blasting cap 19 then is installed on the perforating gun of each oil reservoir, and these electric initiators up are spaced from the shaft bottom, and defer time reaches as high as 6000ms; After reaching the appointment oil reservoir; Cast the electric energy rod at well head, and after connecting with uppermost electric initiator, the electric match 18 of all electric initiators is lighted a fire simultaneously; Because the defer time of time-delay blasting cap 19 is different; So electric initiator from the bottom to top at interval time-delay detonate, can reduce therefore that perforating bullet explodes simultaneously and the detonation pressure that produces to the destruction of oil well casing, whether the ground instrument perforating gun that can monitor each oil reservoir all detonates simultaneously.
