Description
Technical field
The utility model relates to the swirl-flow devices inside a kind of fluid-transporting tubing, more particularly to one kind to be suitable for oil field collection
The liquid liquid swirl-flow devices of defeated pipeline.
Background technique
Petroleum resources are that one of most important energy in China, oil-gas gathering and transferring technology and technology account for during petroleum resources utilize
According to critical role.On the one hand, crude oil in China has the " three high " characteristic of typical high condensation point, high viscosity and high-content wax, extraction
Crude quality is relatively poor, and the glutinous gelatinous crude oil of height considerably increases the difficulty of pipeline, the safety economy of the glutinous gelatinous crude oil of height
Pipeline is current problem in the urgent need to address.On the other hand, as oil-gas field of China exploitation subsequently enters the middle and later periods, often
Oil-gas reservoir recovery ratio is improved using the methods of displacement of reservoir oil by filling water, the steam injection displacement of reservoir oil, these methods directly result in oil gas field extraction again
The moisture content of liquid gradually increases；Based on this, oil field gathering and transportation pipeline uses liquid liquid cyclone separation device, goes out well using oil-water mixture
Pressure of having more than needed after mouthful pushes the rotation of swirl-flow devices guide vane, realizes the cyclonic separation of grease, and outer ring water ring is formed in pipeline
The special flow regime for surrounding inner ring crude oil, substantially reduces the frictional resistance of pipeline, and it is high glutinous to become a kind of solution
The defeated feasible program of gelatinous crude oil safety economy pipe improves the transfer efficiency of crude oil gathering line.And it is current, foreign countries are based on
Cyclone technique successfully develops downhole oil-water separation hydrocyclone, practice have shown that, this downhole oil-water separation hydrocyclone
Split ratio and separative efficiency with higher.Cyclone separation process passes through centrifugal force as an efficient multi-phase separation technology
Effect, realized using the density contrast between two-phase or multiphase medium fluid separate.
Utility model content
The utility model is to be directed to deficiency of the prior art, and provide a kind of which has a compact structure and a reasonable design, is applicable in
A kind of wide and energy-efficient liquid liquid swirl-flow devices for oil field gathering and transportation pipeline of property.
To achieve the goals above, the utility model provides a kind of liquid liquid eddy flow dress suitable for oil field gathering and transportation pipeline
It sets, including the guide vane for cyclonic separation grease, one end of the guide vane center and shaft is connected, the shaft
The other end is connect with bearing, and middle (center) bearing is mounted on the center of rotary support, and the rotary support is fixed on pipeline.
Wherein, the guide vane selects orthogonal bus type blade, the number of blade 4, the exit angle of directrix inside and outside blade
It is 15 °.
The pivot design is multi-segment structure, and No. 45 steel of material selection carry out modifier treatment.
The bearing is tapered roller bearing.The rotary support is fixed on pipeline, and being used to support bearing makes water conservancy diversion leaf
Piece makes rotating motion, and realizes the cyclonic separation to grease, forms the special flowing shape that pipeline Internal and external cycle water ring surrounds inner ring crude oil
State substantially reduces the defeated frictional resistance of pipe.
When work, utility model device is mounted on inside oil field gathering and transportation pipeline, oil-water mixture goes out after well head by certainly
Body is had more than needed pressure, and the guide vane of swirl-flow devices is pushed to rotate, and guide vane high speed rotation forms centrifugation, in the effect of centrifugal force
Under, the different liquid of density can be separated voluntarily, and in outer ring, the small liquid of density can revolve the big liquid meeting eddy flow of density in inner ring
Stream, to realize the cyclonic separation to grease.Therefore inside gathering line, water ring flow forward around tube wall, crude oil exists
Pipeline center's flow forward, so that frictional resistance when reducing Crude Oil Transportation, improves transfer efficiency.
The beneficial effect of this programme can according to the description of the above program, and structure is simple, and design rationally, is easy to tear open
Dress, energy-saving, applicability is wide；Inside is connect by shaft with rotary support using orthogonal bus type guide vane, by stream
Body itself is had more than needed pressure-driven, for the crude oil pipeline of different tube diameters, when crude oil pressure reaches a timing in pipeline, can be achieved
The cyclonic separation of grease forms the special flow regime that outer ring water ring surrounds inner ring crude oil in pipeline, substantially reduces pipeline
The frictional resistance of conveying improves crude oil gathering line delivery safety and efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；
In figure, 1, guide vane；2, shaft；3, bearing；4, rotary support.
Specific embodiment
This programme is illustrated below by specific embodiment for the technical characterstic that can illustrate this programme.
As shown in Figure 1, the utility model is a kind of liquid liquid swirl-flow devices suitable for oil field gathering and transportation pipeline, including for revolving
The guide vane structure 1 of flow separation grease, guide vane select orthogonal bus type blade, the number of blade 4, directrix inside and outside blade
Exit angle is 15 °, the high speed rotation under fluid pressure effect in pipeline.
Guide vane center is connect with one end of shaft 3, and pivot design is multi-segment structure, and No. 45 steel of material selection carry out
Modifier treatment, the shaft other end are connect with bearing 3, and the bearing is tapered roller bearing, and middle (center) bearing is embedded in rotary support 4
Center, the rotary support is fixed on pipeline.
When work, utility model device is mounted on inside crude oil gathering line, after oil-water mixture goes out well head
By pressure of itself having more than needed, the guide vane of swirl-flow devices is pushed to rotate, guide vane high speed rotation forms centrifugation, in centrifugal force
Under effect, the different liquid of density can be separated voluntarily, and for the big liquid meeting eddy flow of density in outer ring, the small liquid of density can be in inner ring
Eddy flow, to realize the cyclonic separation to grease.Therefore inside gathering line, water ring flow forward around tube wall, crude oil
Heart flow forward in the duct, so that frictional resistance when reducing Crude Oil Transportation, improves transfer efficiency.
