Abstract
The utility model discloses a porous injection fracturing head for fracturing well head equipment, which comprises a fracturing head body. The porous injection fracturing head is characterized in that four injection ports are connected with the fracturing head body, and the displacement of each injection port is 4M<3>/min. The upper injection port and the lower injection port are symmetrically arranged, the left injection port and the right injection port are symmetrically arranged, and an opening connected with a well head equipment main pipeline is arranged at the middle part of the fracturing head body. The included angle formed by the left injection port and the opening is 60 degrees, and the included angle formed by the right injection port and the opening is 60 degrees. The utility model solves the problems that the existing fracturing injection equipment is large in size, heavy in weight, high in cost, inconvenient to install, low in fracturing efficiency and short in service life, and provides a porous injection fracturing head for fracturing well head equipment, which has the advantages of compact structure, small volume, light weight, convenience in installation and construction, high fracturing efficiency and longer service life, and is applicable to large displacement range, high in strength and cheap.
Description
Technical field
The utility model belongs to oil exploration equipment device field, particularly relates to a kind of fracture well head equipment and injects fracturing head with porous.
Background technology
Shale gas is receiving increasing concern as a kind of emerging unconventional resource.Such reservoir densification is hard, has the characteristics of low-porosity, low-permeability, for obtaining industrial gas, generally need carry out the staged fracturing modification operation.Shale gas pressure break scale is big, and the individual layer fluid volume is about 2000 sides, and pressure is 25～40MPa, discharge capacity 10～16m
3/ min, and 8～10 sections constructions of the general branch of horizontal well.Require wellhead equipment can carry out big discharge capacity and inject, compressive resistance is high, and can long working.In fracturing process, must use the pressure break injection device like this, but present two four-way junction of casing exist volume bigger, quality is heavy, and cost is high, and shortcomings such as inconvenience are installed.And the parallel multistage fracturing head, when carrying out the construction of big discharge capacity, the hydraulic loss that the collision of the injection flow of both sides produces is bigger, has reduced pressure break efficient, when carrying out big discharge capacity construction simultaneously the fracturing head body is washed away greatlyyer, causes the damage of fracturing head easily.
The utility model content
Pressure break injection device volume in the prior art is big, quality is heavy, cost is high, installations is inconvenient, pressure break efficient is low in order to solve, the short problem in application life, the utility model provides that a kind of compact conformation, volume are little, light weight, be convenient to that installation, pressure break efficient are high, application life the fracture well head equipment than length inject fracturing head with porous.
In order to address the above problem, the technical scheme that the utility model is taked is:
A kind of fracture well head equipment injects fracturing head with porous; Comprise the fracturing head body; It is characterized in that: on the fracturing head body, be connected with four inlets; The said inlet of going up is symmetrical set with following inlet, and said left inlet and right inlet are symmetrical set, and are provided with the opening that is connected with the wellhead equipment main line at fracturing head body medium position.
Aforesaid a kind of fracture well head equipment injects fracturing head with porous, it is characterized in that: said each inlet discharge capacity is 4M3/min.
Aforesaid a kind of fracture well head equipment injects fracturing head with porous, it is characterized in that: the angle of said left inlet and opening is 60 °, and the angle of said right inlet and opening is 60 °.
The beneficial effect of the utility model is: it is big that the utility model fracture well head equipment injects fracturing head adaptation discharge capacity scope with porous, and intensity is high, low price.Compare with two four-way junction of casing, compact conformation, volume are little, light weight, be convenient to installation.Compare with the parallel multistage fracturing head, the hydraulic loss that the flow collision produces is injected in both sides in the time of can reducing the construction of big discharge capacity, and flow is less to washing away of fracturing head body simultaneously, and application life is longer.
Description of drawings
Fig. 1 is that the utility model fracture well head equipment injects the fracturing head structural representation with porous.
Fig. 2 is the longitudinal sectional view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further description.
Shown in Fig. 1-2, a kind of fracture well head equipment injects fracturing head with porous, comprises fracturing head body 1, is being connected with inlet 2, following inlet 3, left inlet 4 and right inlet 5 on the fracturing head body 1.Last inlet 2 is symmetrical set with following inlet 3, and left inlet 4 is symmetrical set with right inlet 5, is provided with the opening 6 that is connected with the wellhead equipment main line at fracturing head body 1 medium position.Each inlet discharge capacity is 4M
3/ min.Left side inlet 4 is 60 ° with the angle of opening 6 (being the wellhead equipment main line), and right inlet 5 is 60 ° with the angle of opening 6 (being the wellhead equipment main line).
During use, on wellhead equipment main line CHF, connect a hydraulic operated valve, after connect this fracturing head; Above fracturing head, connect a hydraulic operated valve again; According to operating mode termination production tree or perforation lubricator on hydraulic operated valve above the fracturing head, so just can carry out pressure break work at last, whole fracturing head discharge capacity scope is big; Intensity is high, low price.
More than show and described basic principle, principal character and the advantage of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (3)
1. a fracture well head equipment injects fracturing head with porous; Comprise the fracturing head body; It is characterized in that: on the fracturing head body, be connected with four inlets; The said inlet of going up is symmetrical set with following inlet, and said left inlet and right inlet are symmetrical set, and are provided with the opening that is connected with the wellhead equipment main line at fracturing head body medium position.
