Description
Technical field：
The utility model belongs to field mining equipment technical field, and in particular to a kind of multistage delay for plug-removing device
Through-bulkhead initiator.
Background technology：
In lasting exploitation, Oil/gas Well hole condition environment can be because of the inorganic scale in well liquid, organic deposition and bacterium dirt etc. in oil field
Deposition fouling, generate different degrees of injury to producing well hole condition, some oil wells feed flow deficiency, in well injection pressure
Rise.Because seepage channel caused by the various factors of oil reservoir blocks, make profit flowing in oil reservoir not smooth, and release and block, recover
（Expand）Seepage channel, it is exactly one of measure of Oil/gas Well middle and later periods volume increase.High energy negative pressure deblocking device can efficiently solve
Above mentioned problem, and gradually applied in oilfield exploitation.So a kind of multistage delay for high energy negative pressure deblocking device of design every
Plate initiator is very necessary.
Utility model content：
The utility model is made up and improved in place of above-mentioned the deficiencies in the prior art, there is provided a kind of for the more of plug-removing device
Level delay through-bulkhead initiator, solves the time difference of high energy negative pressure deblocking device multistage detonation and the sealing problem of cell arrangement,
The quality of negative pressure deblocking is improved, it is reasonable in design, securely and reliably.
The technical solution adopted in the utility model is：A kind of multistage delay through-bulkhead initiator for plug-removing device, should be every
Plate initiator include transmission detonation joint, small isolating cap, delay detonator, locking cap, locking jackscrew, housing, big isolating cap, spacer member,
Dividing plate detonator and supporting sleeve；Supporting sleeve equipped with big isolating cap is connected by screw thread with spacer member, and spacer member is located at housing
Interior and sealed by O-shaped O-ring seal, the small isolating cap and delay detonator after assembling are located in two symmetrical holes of transmission detonation joint,
And be locked by locking cap, transmission detonation joint is threadedly coupled with housing；The dividing plate detonator is located in supporting sleeve.
The transmission detonation joint is provided with flexible linear shaped charge winding groove.
The spacer member scribbles stop-leak compound after being sealed with housing by O-shaped O-ring seal.
The transmission detonation joint is provided with top wire hole.
The beneficial effects of the utility model：A kind of multistage delay through-bulkhead initiator for plug-removing device is provided, solved
The detonation problem of high energy negative pressure deblocking device, the quality of negative pressure deblocking is improved, it is reasonable in design, securely and reliably.Prolonged by combining
When igniting, the technical advantage of dynamic negative-pressure and high enegry gas fracturing, utilize high temperature and high pressure gas caused by real-time powder burning, burn
The pollutants such as wax, colloid in erosion melting well, while gases at high pressure produce high-pressure area near wellbore formation.Then by design
The negative pressure cab that time delayses are opened, can ensure high pressure caused by propellant of high energy to the action time of nearly well rock stratum, and the high pressure that staggers is made
With the negative pressure cab opened again after the time so that in well, the near wellbore formation rapid pressure drop of construction section, produce from perforation tunnel to
The gas-liquid backflow of high temperature and high speed in well, in stratum in the high speed reflux course of high temperature gas-liquid, strong flushing cleaning stratum
Rock gap and the deposit of perforation tunnel, it can make to treat christmas smooth seepage flow between perforation tunnel between rock gap after effect, realize
Produce the recovery of hole condition environment.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
Reference picture 1, a kind of high energy negative pressure deblocking device, multistage delay through-bulkhead initiator 6 include transmission detonation joint 14, small isolation
Cap 23, delay detonator 15, locking cap 16, locking jackscrew 22, housing 17, big isolating cap 18, spacer member 19, dividing plate detonator 20 and branch
Support set pipe 21；Supporting sleeve 21 equipped with big isolating cap 18 is connected by screw thread with spacer member 19, and spacer member 19 is located at housing 17
Interior and sealed by O-shaped O-ring seal, be located at transmission detonation joint 14 two of the small isolating cap 23 and delay detonator 15 after assembling are right
Claim in hole, and be locked by locking cap 16, transmission detonation joint 14 is threadedly coupled with housing 17；The dividing plate detonator 20 is positioned at branch
In support set pipe 21；The transmission detonation joint 14 is provided with flexible linear shaped charge winding groove；The spacer member 19 passes through O-shaped fluid sealant with housing 17
Stop-leak compound is scribbled after circle sealing；The transmission detonation joint 14 is provided with top wire hole.
First, multistage delay initiator assemble sequence
Big isolating cap 18 is inserted in supporting sleeve 21 first, then by the supporting sleeve 21 equipped with big isolating cap 18 be screwed into every
Plate body；O-shaped O-ring seal is inserted in the seal groove of spacer member 19, smears stop-leak compound, then the single piece that the first step is assembled,
Load from the end of thread endoporus of the Tr90 of housing 17 × 4 in ∮ 30 sealing hole；Small isolating cap 23 and delay detonator 15 are assembled one
Rise, in the hole for two symmetrical M14 for loading transmission detonation joint 14, then locking cap 16 is screwed into M14 screwed hole；By M6 top
