Description
Technical field
The utility model relates to natural gas extraction fields, and in particular to a kind of spiral flow-guiding device for gas recovery well.
Background technique
Natural gas is widely used as a kind of clean energy resource in industry and huge numbers of families.Natural gas is imbedded in gas field
Underground, need that natural gas is collected ground from stratum by gas extraction system, each city be then transported to by pipeline
Natural gas station, it is for people to use by natural gas station again by natural gas transportation to huge numbers of families.
With deeply will appear hydrops in gas well bottom to gas well exploitation is gradual, in gas production process part hydrops with
The extraction of natural gas be adhered in pit shaft, some sediments and other substances are adhered on shaft in wall also with hydrops,
It will lead to pit shaft blocking when serious, the strong influence quantum of output of natural gas, therefore design a kind of spiral for gas recovery well
Guiding device be it is very necessary, shaft in wall cleaning problems in gas production process are solved by the gas production mode of spiral stream guidance.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of spiral flow-guiding devices for gas recovery well, originally
Utility model guiding device structure is simple, small in size, easy to disassemble to be used for multiple times, and can be applied to the well site or sea of various environment
Platform can be such that pipeline internal medium conveys in eddy flow, and reducing to block simultaneously has effects that certain cleaning shaft in wall, reduction gas production at
This, increases gas production efficiency.
The utility model embodiment provides a kind of spiral flow-guiding device for gas recovery well, including fixed ring, spiral stream guidance
Band, gas passage, guiding device outer wall, guiding device inner wall, fixed ring are located at guiding device inner wall both ends, guiding device inner wall
It is connect by spiral stream guidance band with guiding device outer wall, gas passage is between guiding device outer wall and guiding device inner wall.
The spiral stream guidance band material is anticorrosion stainless steel.
There is antiseptic rubber coating on the guiding device outer wall, can be fitted closely with internal surface of sleeve pipe in gas recovery well.
In use, the spiral stream guidance band can be such that medium in oil jacket annulus conveys in eddy flow, eddy flow conveys the utility model
Relatively common advection conveying has stronger advantage, and when medium flows through pipeline in petroleum pipeline, medium will be in spiral stream guidance band
Under the action of, tangential velocity is generated, screw is become from the axial movement of script, under spiral stream mode, can avoid precipitating
Object and other substances, which are adhered on pipeline, causes pit shaft to block, and has effects that certain cleaning tube inner wall.
A kind of spiral flow-guiding device beneficial effect for gas recovery well of the utility model embodiment is: 1) the utility model
Spiral flow-guiding device structure is simple, small in size, easy to disassemble to be used for multiple times, and can be applied to the well site or marine flat of various environment
Platform；2) the utility model spiral flow-guiding device can be such that medium in oil jacket annulus conveys in eddy flow, reduce and block and have centainly
Shaft in wall effect is cleaned, gas production cost is reduced, increases gas production efficiency；3) it is fixed on oil pipe when the utility model is used
It can be used, maintenance cost is extremely low.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model

Other attached drawings.
Fig. 1 is the utility model top view.
Fig. 2 is the utility model outside drawing.
Fig. 3 is the utility model section figure.
Drawing reference numeral: 1, fixed ring 2, spiral stream guidance band 3, gas passage 4, guiding device outer wall 5, guiding device inner wall 6,
Oil pipe 7, casing.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1-3, the utility model includes fixed ring 1, spiral stream guidance band 2, gas passage 3, guiding device outer wall
4, guiding device inner wall 5, fixed ring 1 are located at 5 both ends of guiding device inner wall, and guiding device inner wall 5 passes through spiral stream guidance band 2 and leads
It flows device outer wall 3 to connect, gas passage 3 is between guiding device outer wall 4 and guiding device inner wall 5
When the utility model is used, oil pipe 6 is passed through into spiral flow-guiding device, keeps oil-pipe external wall and guiding device inner wall 5 tight
Closely connected conjunction, the fixed ring 1 at fixed 5 both ends of guiding device inner wall, is fixed on spiral flow-guiding device on oil pipe 6, by 6 tripping in of oil pipe
In gas recovery well, guiding device outer wall 4 is fitted closely in gas recovery well with 7 inner wall of casing, starts gas production operation.
When the utility model is used, spiral stream guidance dress can accordingly be adjusted according to the size of practical gas recovery well oil pipe, casing
The size set fit closely it can with casing, oil pipe.
Particular embodiments described above has carried out into one the purpose of this utility model, technical scheme and beneficial effects
Step is described in detail, it should be understood that being not used to limit this foregoing is merely specific embodiment of the utility model
The protection scope of utility model, within the spirit and principle of the utility model, any modification for being made, changes equivalent replacement
Into etc., it should be included within the scope of protection of this utility model.
