Abstract
The utility model relates to a detonator joint of a perforating gun in petroleum production. The detonator joint mainly solves the problems of complicated structure and operation in the existing detonator joint. The detonator joint is characterized in that a joint body (1) is connected with a detonator (2) by a thread, the bottom of the joint body (1) and the hole bottom of the inside of the detonator (2) are provided with a detonating cord extending length A, a centralizing body (3) is arranged in an axial center hole of the detonator (2), a detonating pipe (5) is arranged in the upper part of an axial hole of the centralizing body (3) and is fixed by a jackscrew (6), and a detonating cord (4) is arranged in the lower part of the axial hole of the centralizing body (3). The detonator joint of the perforating gun in petroleum production has the advantage that the structure and the operation are simple.
Description
Technical field:
The utility model relates to the initiator joint on the used joint of perforating gun, especially the petroleum recovering perforating gun in the oil extraction in oil field field.
Background technology:
In the oil extraction in oil field field, perforation is the important process before the petroleum recovering.When perforating job, need to use perforating gun.The initiator joint is the vitals of perforating gun.And have the initiator joint now because there is the problem of structure and complicated operation in reasons in structure, in order to guarantee the propagation of explosion rate, the staff will carefully measure each detonating fuse head extension elongation, affects perforating job efficient and quality.
The utility model content:
In order to solve the problem of existing initiator joint design and complicated operation.The utility model provides the initiator joint on a kind of petroleum recovering perforating gun.Initiator joint on this petroleum recovering perforating gun has structure and characteristics simple to operate.
The technical solution of the utility model is: the initiator joint on this petroleum recovering perforating gun comprises joint body, initiator, centralizer body, detonating fuse, detonating primer and jackscrew.Joint body is connected with initiator by screw thread, the detonating fuse of setting extension elongation A is arranged at the bottom of joint body bottom surface and the initiator endoporus, centralizer body places in the initiator hole axially placed in the middle, detonating primer places in the centralizer body axial hole top, and fix by jackscrew, detonating fuse places in the centralizer body axial hole bottom.
The utlity model has following beneficial effect: the initiator joint on this petroleum recovering perforating gun is owing to adopt joint body to be connected with initiator by screw thread, the detonating fuse of setting extension elongation A is arranged at the bottom of joint body bottom surface and the initiator endoporus, centralizer body places in the initiator hole axially placed in the middle, detonating primer places in the centralizer body axial hole top, and fix by jackscrew, detonating fuse places the structure in the centralizer body axial hole bottom.Setting detonating fuse extension elongation A between utilizing at the bottom of joint body bottom surface and the initiator endoporus, detonating fuse head extension elongation reduces and carefully measures number of times, thereby simplified structure, attended operation is convenient, guarantees propagation of explosion rate and perforating job personnel's safety, and reduces cost.Initiator joint on this petroleum recovering perforating gun has structure and characteristics simple to operate thus.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
1-joint body among the figure, 2-initiator, 3-centralizer body, 4-detonating fuse, 5-detonating primer, 6-jackscrew.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the initiator joint on this petroleum recovering perforating gun comprises joint body 1, initiator 2, centralizer body 3, detonating fuse 4, detonating primer 5 and jackscrew 6.Joint body 1 is connected with initiator 2 by screw thread, the detonating fuse of setting extension elongation A is arranged at the bottom of joint body 1 bottom surface and initiator 2 endoporus, the propagation of explosion of setting distance A is namely arranged at the bottom of joint body 1 bottom surface and initiator 2 endoporus, set detonating fuse extension elongation A according to design setting, centralizer body 3 places in initiator 2 holes axially placed in the middle, detonating primer 5 places in the centralizer body 3 axial hole tops, and fixing by jackscrew 6, and detonating fuse 4 places in the centralizer body 3 axial hole bottoms.
During actual the use, joint body 1 is with after initiator 2 has been connected, detonating fuse 4 is pressed centralizer body 3 customized cut-offs, dock with detonating primer 5 again, insert in the centralizer body 3 axial hole tops, detonating primer 5 end faces and centralizer body 3 joint bodies 1 bottom surface are pushed away concordant, fixing with jackscrew 6, namely finish initiator operation on the perforating gun.Initiator joint on this petroleum recovering perforating gun is compared with existing initiator joint, and is lower to cutting off detonating fuse 4 length requirements, and only centralizer body 3 reeve initiators 2 joint interstitial holes got final product on earth, makes more convenient operation, connects rapider.
Claims (1)
1. the initiator joint on the petroleum recovering perforating gun, comprise joint body (1), initiator (2), centralizer body (3), detonating fuse (4), detonating primer (5) and jackscrew (6), it is characterized in that: joint body (1) is connected with initiator (2) by screw thread, the detonating fuse of setting extension elongation A is arranged at the bottom of joint body (1) bottom surface and initiator (2) endoporus, centralizer body (3) places in initiator (2) hole axially placed in the middle, detonating primer (5) places in centralizer body (3) the axial hole top, and fixing by jackscrew (6), detonating fuse (4) places in centralizer body (3) the axial hole bottom.
