Description
Technical field
The utility model relates to the technical field of perforating gun structure, especially a kind of quick change non junction perforating gun.
Background technique
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 with multiple mounting holes on firing mount pipe and along its length, 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 forming 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, its both ends need to be connected respectively on the outer gun barrel of two perforating guns, be existed when jointing
The low defect of joint efficiency additionally needs to maintain so polylinker, increases cost of upkeep.
In addition, firing mount pipe is fixed in outer gun barrel by flange, not only assembly difficulty, but also need 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 disposably, to make
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.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provide it is a kind of it is compact-sized, improve joint efficiency,
Instead of the connection of original connector, quick change non junction perforating gun.
The purpose of this utility model is achieved through the following technical solutions: a kind of quick change non junction perforating gun, it includes outer
Gun barrel and firing mount pipe are provided on the cylinder of the outer gun barrel and along its length blind hole in spiral distribution, firing mount pipe
It is provided on cylinder and along its length in spiral distribution for installing the mounting hole of body, mounting hole is corresponding with blind hole,
It is characterized by: offering external screw thread on the outer wall of the outer gun barrel right part, offered on the inner wall of outer gun barrel left part interior
Screw thread is also provided with keyway on the inner wall of the left part of outer gun barrel, which further includes left positioning disk and right positioning disk, Zuo Ding
Position disk and right positioning disk are multi-diameter shaft, and centre bore, one end of the firing mount pipe are offered in left positioning disk and right positioning disk
It is sheathed 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, the both ends screw thread of firing mount pipe
It is connected with lock-screw, lock-screw is through firing mount pipe and presses on small axis, is installed with limit spiral shell on the big axis of left positioning disk
The big axis of nail, the left positioning disk and right positioning disk is all set in outer gun barrel, and the stop screw of left positioning disk is set to key
It is rotated in slot with limiting left positioning disk.
The outer gun barrel and firing mount pipe are coaxially disposed.
The width of the keyway and the width of stop screw are equal.
The utility model has the advantage that the utility model is compact-sized, improves joint efficiency, instead of original connector
Connection is maintained without butt joint.

Specific embodiment
The utility model is further described with reference to the accompanying drawing, the protection scope of the utility model be not limited to
It is lower described:
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 is coaxially disposed, and is provided on the cylinder of the outer gun barrel 1 and along its length blind hole 3 in spiral distribution, firing mount pipe 2
Cylinder on and be provided with along its length in spiral distribution for installing the mounting hole 4 of body, mounting hole 4 and blind hole 3
It is corresponding, it is characterised in that: external screw thread 5 to be offered on the outer wall of outer 1 right part of gun barrel, on the inner wall of outer 1 left part of gun barrel
Internal screw thread 6 is offered, is also provided with keyway 7 on the inner wall of the left part of outer gun barrel 1, which further includes left 8 He of positioning disk
Right positioning disk 9, left positioning disk 8 and right positioning disk 9 are multi-diameter shaft, offer centre bore in left positioning disk 8 and right positioning disk 9
10, one end of the 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 right positioning disk 9
On small axis, 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,
