Description
Technical field
The present invention relates to the technical field of perforating gun structure, especially a kind of quick change non junction perforating gun.
Background technology
Perforating gun is important devices indispensable in oil exploitation.Perforating gun includes outer gun barrel, firing mount pipe and perforation
Bullet, firing mount pipe are set in outer gun barrel, are provided on firing mount pipe and along its length multiple mounting holes, mounting hole is twist
It is distributed on firing mount pipe, is mounted on perforating bullet in each mounting hole, offer on the outer gun barrel and along its length more
A blind hole, blind hole are twist distributed on outer gun barrel, and each blind hole corresponds to a perforating bullet.Since the depth of oil well is long
Up to 100 ~ 200m, it is therefore desirable to more perforating guns are together in series by connector after composition pipe string and are lowered into oil well again, and it is every
The length of the independent perforating gun of root only has 2 ~ 3m, it is therefore desirable to could be connected these independent perforating guns using 50 ~ 68 connectors
It picks up to form pipe string.However, when jointing, its both ends need to be connected respectively on the outer gun barrel of two perforating guns, be existed
The low defect of joint efficiency also needs to maintain so polylinker in addition, increases cost of upkeep.
In addition, firing mount pipe is fixed on by flange in outer gun barrel, not only assembly is difficult, but also needs to connect many screws
Firing mount pipe can be fixed in outer gun barrel, there are connection labor intensity, and the connection period is long, the low defect of joint efficiency.
Perforating bullet is disposable explosive, can be scraped using rear firing mount pipe, therefore firing mount component is disposable, is made
It is handled with rear direct calcellation, positioning disk or firing mount pipe will not be further taken out, gun barrel is typically also to abandon after use, traditional approach
Center tap can remove and reused after cleaning and maintenance.
Invention content
It is an object of the invention to overcome the prior art, compact-sized one kind, raising joint efficiency, replacement are provided
Original connector connection, quick change non junction perforating gun.
The purpose of the present invention is achieved through the following technical solutions：A kind of quick change non junction perforating gun, it includes outer gun barrel
With firing mount pipe, it is provided on the cylinder of the outer gun barrel and along its length blind hole in spiral distribution, the cylinder of firing mount pipe
It is provided with above and along its length the mounting hole for installing body in spiral distribution, mounting hole is corresponding with blind hole, special
Sign is：External screw thread is offered on the outer wall of the outer gun barrel right part, and internal thread is offered on the inner wall of outer gun barrel left part,
It is further opened with keyway on the inner wall of the left part of outer gun barrel, which further includes left positioning disk and right positioning disk, left positioning disk
It is multi-diameter shaft with right positioning disk, centre bore is offered in left positioning disk and right positioning disk, one end of the firing mount pipe is arranged
In on the small axis of left positioning disk, the other end of firing mount pipe is sheathed on the small axis of right positioning disk, and the both ends of firing mount pipe are threadedly coupled
There is lock-screw, lock-screw is through firing mount pipe and presses on small axis, is installed with stop screw on the big axis of left positioning disk, institute
The big axis for stating left positioning disk and right positioning disk may be contained in outer gun barrel, and the stop screw of left positioning disk be set in keyway with
Left positioning disk is limited to rotate.
The outer gun barrel is coaxially disposed with firing mount pipe.
The width of the keyway is equal with the width of stop screw.
The present invention has the following advantages：Structure of the invention is compact, improves joint efficiency, instead of the connection of original connector, nothing
Butt joint is needed to be maintained.

Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below：
As shown in Fig. 1 ~ 5, a kind of quick change non junction perforating gun, it includes outer gun barrel 1 and firing mount pipe 2, outer gun barrel 1 and firing mount pipe 2
It is coaxially disposed, is provided on the cylinder of the outer gun barrel 1 and along its length blind hole 3 in spiral distribution, the column of firing mount pipe 2
It is provided on face and along its length the mounting hole 4 for installing body in spiral distribution, mounting hole 4 is corresponding with blind hole 3,
It is characterized in that：External screw thread 5 is offered on the outer wall of 1 right part of outer gun barrel, is offered on the inner wall of 1 left part of outer gun barrel
Internal thread 6 is further opened with keyway 7 on the inner wall of the left part of outer gun barrel 1, which further includes left positioning disk 8 and right positioning
Disk 9, left positioning disk 8 and right positioning disk 9 are multi-diameter shaft, and centre bore 10, institute are offered in left positioning disk 8 and right positioning disk 9
The one end for stating firing mount pipe 2 is sheathed on the small axis of left positioning disk 8, and the other end of firing mount pipe 2 is sheathed on the small axis of right positioning disk 9
On, the both ends of firing mount pipe 2 are threaded with lock-screw 11, and lock-screw 11 is through firing mount pipe 2 and presses on small axis, Zuo Ding
It is installed with stop screw 12 on the big axis of position disk 8, the big axis of the left positioning disk 8 and right positioning disk 9 may be contained within outer gun barrel 1
In, and the stop screw 12 of left positioning disk 8 is set in keyway 7 and is rotated with limiting left positioning disk 8.
The width of keyway 7 described in the present embodiment is equal with the width of stop screw 12.
The course of work of the present invention is as follows：When more perforating guns are connected into pipe string, by the outer gun barrel 1 of perforating gun A14
External screw thread 5 be threadedly coupled with the internal thread 6 of the outer gun barrel 1 of perforating gun B15 as shown in fig. 6, to which two perforations be rapidly completed
The connection of rifle so operates, you can the head and the tail series connection for completing more perforating guns, to be connected using connector instead of original
It connects, is maintained without butt joint, be greatly saved cost, while can also reuse.
