Description
Technical field
The utility model relates to field of oil drilling, and in particular to a kind of cable priming device.
Background technique
An important branch of the cable transmission perforation as perforating technology is widely used in the perforation scene in each market
In operation, have many advantages, such as short construction period, mature technology.With the raising of oil-gas mining technology, the peace of perforating job
For full property by extensive concern, the traditional connection type of cable transmission perforation mode gradually exposes its drawback in safety.Tradition is even
Connecing is that assembled perforating gun is first reserved certain length primacord to fix with Magnedat, and two conducting wires of detonator pass through gun barrel
After (detonator storehouse) is connected and fixed with big gun head lead, the locator connector of cable is connected.Which unfavorable factor is as follows: 1)
It needs to connect the stronger Magnedat conducting wire of sensibility at the scene in construction.2) after first firer electrician linker.3) big gun head falls
Detonator line easily plays torsion damage and causes to do over again when button is screwed into gun barrel.It is more that the connection type is disturbed factor, operates relative complex, causes
Construction success rate is far below oil tube transmission perforation mode.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of cable priming device, is able to achieve Magnedat
Quick connection and first electrician after firer secure connection program, greatly improve construction safety degree and success rate.
For this purpose, the technical solution of the utility model is as follows:
A kind of cable priming device, including contact Magnedat, detonator seat, sealed contact pin and detonator pressure cap；
The sealed contact pin is sealingly mounted at one end of the detonator seat；
The two poles of the earth of the contact Magnedat are respectively shell and unipods contact pin, are mounted on detonator by detonator pressure cap
The other end of seat, meanwhile, only angle contact pin of the contact Magnedat is inserted into inside the sealed contact pin.
Sealed contact pin is water proof sealing element, prevents after blasting cap initiation borehole pressure to enter magnetic localizer along channel and causes
Damage.
Further, the contact Magnedat be contact, an extremely shell by two traverse designs of Magnedat
Body, another extremely unipods contact pin.
Further, the junction of the sealed contact pin and the detonator seat is equipped with sealing ring.
The cable priming device is not exposed to outer conducting wire, and the scene of being not required to connects Magnedat conducting wire, is able to achieve magnetoelectricity thunder
The secure connection program of the quick connection of pipe and firer after first electrician, greatly improves construction safety degree and success rate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of cable priming device provided by the utility model；
Fig. 2 is the explosive view that cable priming device provided by the utility model removes detonator pressure cap；
Fig. 3 is the usage state diagram of cable priming device provided by the utility model.
Specific embodiment
The technical solution of the utility model is described in detail below in conjunction with the drawings and specific embodiments.
A kind of cable priming device, including contact Magnedat 2, detonator seat 1, sealed contact pin 3 and detonator pressure cap 4；
Sealed contact pin 3 is sealingly mounted at one end of detonator seat 1；The two poles of the earth of contact Magnedat 2 are respectively shell and unipods contact pin,
Its other end that detonator seat 1 is mounted on by detonator pressure cap 4, meanwhile, only angle contact pin insertion of contact Magnedat 2 is sealed
Inside contact pin 3.Sealed contact pin 3 is water proof sealing element, and borehole pressure is prevented after blasting cap initiation to enter magnetic localizer along channel
It damages.The junction of sealed contact pin 3 and detonator seat 1 is equipped with sealing ring.
Specifically, contact Magnedat 2 be contact, an extremely shell by two traverse designs of Magnedat
Body, another extremely unipods contact pin.
In use, sealed contact pin 3 is fitted into detonator seat 1, outwardly, interior contact is towards 1 direction of detonator seat for contact pin one end.It will
Contact Magnedat 2 is fitted into detonator seat 1, contact one end towards inside detonator seat 2, with the interior contact of sealed contact pin 3 into
Row contact, passes through detonator pressure cap 4 from detonator head and is screwed into detonator seat 1, abundant fixed contact formula Magnedat 2 and detonator seat 1.
The detonator seat 1 assembled is fitted into cable priming device connector 5, detonator supporting positive cover 7 is loaded at detonator, is used for
Guarantee that contact Magnedat is placed in the middle in cable priming device connector 5, it can be abundant with the detonating primer 10 in perforating gun top connection 8
Propagation of explosion.Conductive component 6 is packed into from 5 other end of cable priming device connector again.Conductive component 6 is by two terminal contacts and groups of springs
At, for realizing the Elastic Contact at both ends, prevent contact caused by Hard link be broken or do not connect.
Cable priming device connector 5 is first connected with the magnetic localizer union connector for having connect cable after the assembly is completed
It connects, only understands detonating primer cable occur and surprisingly charging situation at this time, will not detonate perforating gun.It finally reconnects and assembles
After the top connection 8 of perforating gun, integrated connection is realized.
