Abstract
A kind of percussion primer, including upper shell, striker, pin, check ring, striker set, lower house, connector, impact detonator, sealing ring, support set etc., striker is arranged on striker and put, and fixed with pin, striker set is fixed on lower house by check ring, lower house is connected with upper shell, impact detonator is in support set, support is set on connector, connector is arranged in lower house, and is connected with striker set, by changing enclosure interior detonation component, it can again reuse, effectively reduce production cost.The utility model has simple in construction, dependable performance, the low advantage of easy to use, production cost, it is adaptable to the need for a large amount of productions of oil pipeline conveying gun perforation detonation.
Description
Technical field
The utility model belongs to perforating oil gas well detonating technique, and the shock that more particularly to a kind of housing may be reused rises
Quick-fried device.
Background technology
At present, the percussion primer that the major oil pipeline conveying gun perforations of China are used, it is typically all disposable, complete
The housing of initiator can not be reused after into detonation, caused very big waste, added production cost.So the utility model
Devise a kind of simple in construction, dependable performance, the percussion primer that easy to use, housing may be reused, by changing shell
Internal portion's detonation component, can be reused, its cost only has 1/3rd of former initiator, effectively reduces and is produced into again
This.The need for a large amount of productions of oil pipeline conveying gun perforation detonation.
The content of the invention
The purpose of this utility model can not be repeated to solve the housing for the percussion primer that current oil well perforation is used
The technical problem used etc. is fitted there is provided the low percussion primer of a kind of simple in construction, dependable performance, easy to use, production cost
The need for a large amount of productions of oil pipeline conveying gun perforation detonation.
The utility model includes upper shell, striker, pin, check ring, striker set, lower house, connector, shock thunder
Pipe, sealing ring, support set etc., striker is arranged on striker and put, and is fixed with pin, and striker set is fixed on down by check ring
On housing, lower house is connected with upper shell, and impact detonator is in support set, and support set is arranged on connector by screw thread
On, the connector equipped with sealing ring is arranged on lower house, and is connected by screw thread with striker set.
The utility model has simple in construction, dependable performance, the low advantage of easy to use, production cost, it is adaptable to oil field
The need for a large amount of productions of oil tube conveying gun perforation detonation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In Fig. 1：Thunder is hit in 1 upper shell, 2 strikers, 3 pins, 4 check rings, 5 striker sets, 6 lower houses, 7 connectors, 8
Pipe, 9 sealing rings, 10 support sets.
Embodiment
As illustrated, further illustrating organization plan of the present utility model and the course of work with reference to example.
As shown in figure 1, a kind of percussion primer, including upper shell 1, striker 2, pin 3, check ring 4, striker set 5, under
Housing 6, connector 7, impact detonator 8, sealing ring 9, support set 10.
Striker 2 of the present utility model is arranged on striker set 5, and is fixed with pin 3, and striker set 5 is solid by check ring 4
It is scheduled on lower house 6, lower house 6 is connected by screw thread with upper shell 1.Impact detonator 8 is in support set 10, support set
10 are arranged on connector 7 by screw thread, and the connector 7 equipped with sealing ring 9 is arranged on lower house 6, and by screw thread with hitting
Needle guard 5 is connected.Because the lower end cavity of lower house 6 is big, and support set 10 is using cast iron manufacture, its lower end and provided with pre-
Groove processed, when the explosive charge of impact detonator 8, can partly be fried below pregroove marks, and connector 7 and lower house 6 will not be made
Into damage.So explode after detonation component, i.e., striker 2, pin 3, striker set 5, connector 7, hit sealing ring 9 can be under
Taken out in housing 6, the detonation component more renewed, carry out exploding perforating hole next time and use.
The course of work of the present utility model is：The upper shell 1 of initiator is connected with oil pipe when using, lower house 6 is with penetrating
Hole rifle connection, is sent to initiator and perforating gun with oil pipe the specified location of oil well.Then shock rod is cast in well head, hits rod
The free-falling in oil pipe, when shock rod bumps against the striker 2 of initiator, pin 3 is cut, and striker 2 is quick mobile downwards, its
The top of connector 7 is pierced through at tip, and percussion impact detonator 8 explodes, and ignites the detonating primer in perforating gun, propagation of explosion is quick-fried ignite again lead it is quick-fried
Rope, primacord ignites perforating bullet and carries out perforation.After the completion of detonation, and the detonation component more renewed, carry out exploding perforating hole next time
Use.
