Description
[technical field]
The present invention relates to the technical field of fracturing head, the technical field of especially a kind of fracturing head with octahedral outlet.
[background technique]
Shale gas is being received more and more attention as a kind of emerging unconventional resource.Such reservoir is fine and close hard
Firmly, have the characteristics that low-porosity, low-permeability, to obtain industrial gas, generally require and carry out staged fracturing transformation operation.Page
It is big that scale is split in rock air pressure, and single layer fluid volume is 2000 sides or so, and pressure is 25~40MPa, 10~16m of discharge capacity3/ min, and it is horizontal
Well generally divides 8~10 sections of constructions.It is required that wellhead equipment is able to carry out huge discharge injection, compressive resistance is high, and can long working.
It must be used in this way in fracturing process and arrive pressure break injection device, but the conventional structure of current fracturing head such as Fig. 1, if pressed
Such structure designs the fracturing head exported with octahedral, it will keeps product shape larger, heavier-weight, cost increases substantially.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of fracturing head with octahedral outlet is proposed, it can
Reduce shape, mitigate weight, reduces production cost.
To achieve the above object, described the invention proposes a kind of fracturing head with octahedral outlet, including fracturing head ontology
The channel of the upper surface and lower end surface through fracturing head ontology is equipped in fracturing head ontology, the fracturing head ontology is by upper fracturing head
Body and fracturing head body by integral forming are constituted, and the upper fracturing head body and fracturing head body lamination are arranged, the upper fracturing head body
Be all provided on fracturing head body there are four outlet, the outlet is connected to channel.
Adjacent two side of the cube shape preferably, the upper fracturing head body is positive, the upper fracturing head body connects
The place of connecing changes into cambered surface, and 4 sides of the upper fracturing head body respectively set one outlet, and 4 sides of the fracturing head body are respectively set
One outlet, the outlet cross-distribution in outlet and fracturing head body on the upper fracturing head body, the outlet is hung down with channel
Straight setting.
Preferably, being equipped with the screw hole around outlet distribution on the side of the upper fracturing head body and fracturing head body.
Preferably, the upper surface of the upper fracturing head body is equipped with the screw hole that the upper port around channel is distributed.
Preferably, the lower end of the fracturing head body, integrally formed with connector, the lower end of the connector, which is equipped with, inserts
The lower end of junctor, the grafting body is equipped with annular recess.
Beneficial effects of the present invention: the present invention by by fracturing head ontology by upper fracturing head body and fracturing head body one at
Type is constituted, and upper fracturing head body and fracturing head body lamination are arranged, and is all provided on upper fracturing head body and fracturing head body there are four outlet,
Compared with prior art, shape can be reduced, mitigate weight, reduce production cost, production is easy.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.

[specific embodiment]
Refering to Fig. 2,3, a kind of fracturing head with octahedral outlet of the present invention, including fracturing head ontology 1, the fracturing head ontology
The channel 2 of the upper surface and lower end surface through fracturing head ontology 1 is equipped in 1, the fracturing head ontology 1 is by upper 11 He of fracturing head body
Fracturing head body 12, which is integrally formed, to be constituted, and the upper fracturing head body 11 is arranged with 12 lamination of fracturing head body, the upper fracturing head
It is all provided on body 11 and fracturing head body 12 there are four outlet 13, the outlet 13 is connected to channel 2, and the upper fracturing head body 11 is
Square shape, the adjacent two side junction of the upper fracturing head body 11 change into cambered surface, and the 4 of the upper fracturing head body 11
A side respectively sets one outlet 13, and 4 sides of the fracturing head body 12 respectively set one outlet 13, the upper fracturing head body 11
On outlet 13 and 13 cross-distribution of outlet on fracturing head body 12, the outlet 13 be vertically arranged with channel 2, the upper pressure
The screw hole 14 being equipped on the side of a body 11 and fracturing head body 12 around 13 distribution of outlet is split, the upper fracturing head body 11
Upper surface is equipped with the screw hole 14 that the upper port around channel 2 is distributed, and the lower end of the fracturing head body 12 is integrally formed with connection
Body 15, the lower end of the connector 15 are equipped with grafting body 16, and the lower end of the grafting body 16 is equipped with annular recess 17.
The course of work of the present invention:
The present invention it is a kind of with octahedral outlet fracturing head during the work time, by fracturing head ontology 1 by upper fracturing head body 11
It is integrally formed and constitutes with fracturing head body 12, upper fracturing head body 11 is arranged with 12 lamination of fracturing head body, upper 11 He of fracturing head body
It is all provided on fracturing head body 12 there are four exporting 13, compared with prior art, shape can be reduced, mitigate weight, reduce production
Cost, production are easy.
Above-described embodiment is the description of the invention, is not limitation of the invention, after any pair of simple transformation of the present invention
Scheme all belong to the scope of protection of the present invention.
