Description
Technical field
This utility model relates to a kind of underground vortex instrument.
Background technology
Natural gas well shaft bottom hydrops is the common problem during product well development, selects effective water pumping gas production work
Technology, is to extend gas well liquid loading cycle, the key of raising recovery ratio.Eddy-current technique, in the application in oil field, is hydrodynamics
The newest fruits of application, this technology, on the basis of eddy current conveying technology, takes liquid problem for gas well, and according to gas well structure
The characteristic study develops eddy current instrument, and gas well gaslift, reduction tube voltage drop, raising recovery ratio are had remarkable result.It is the most former
Reason is to be changed into vertically upward along tube inner wall direction helical form by original by the motion mode of the medium fluid in oil pipe
Move upward formation spiral helicine eddy current fluidised form.It is the interior of a cylinder or cone that the core of underground vortex instrument is constituted
Entity and the helical blade of outside, its Main Function is the spiral type that will enter the interior segmentation of helical blade between entity and oil pipe
The medium fluid of cavity is accelerated along helicoid, it is achieved changes the direction of motion of fluid and improves the function of flow velocity.But,
Instrument is gone into the well for convenience, the external diameter of helical blade design both less than relevant scope, causes the eddy current instrument can not be complete in down-hole
Fitting with tube inner wall, cause certain media to flow through from gap, for through spiral type cavity, the efficiency of water pumping gas production is relatively low.
Utility model content
The purpose of this utility model is to provide a kind of underground vortex instrument, improves existing eddy current tool exhaust gas production efficiency
Relatively low problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of underground vortex instrument, including the fishing head being from top to bottom sequentially connected with, streams device, guide shell, baffle ring；Described
Stream device outer wall and be provided with the helical blade of projection；Have groove on described helical blade, and this groove extends along helical blade
Two ends to helical blade；It is provided with expansion piece in described groove；In the shape of a spiral, and the external diameter of expansion piece is equal to spiral shell for described expansion piece
The external diameter of vane sheet.
Further, the external diameter of described helical blade is than pipe aperture little 6～8mm.
Yet further, described groove is arranged at the centre of lobe of helical blade.
Further, described expansion piece is to be made by the material of water-swellable.
It addition, described groove both sides are additionally provided with draw-in groove；Described expansion piece both sides are provided with the boss snapping in draw-in groove.
This utility model compared with prior art, has the following advantages and beneficial effect:
Owing to being not added with the eddy current instrument of expansion piece, when fluid is by eddy current instrument, segment fluid flow can pass through instrument and pipe
The space of wall and do not pass through helicla flute, it is impossible to change fluidised form, take outlet capacity relatively low.But this utility model uses at helical-blade
Expansion piece is set on sheet so that eddy current instrument, after going into the well, after the expansion piece water-swellable on helical blade, is fitted in closely
Tube inner wall, makes the fluid by eddy current instrument completely by spiral type cavity, to change its fluidised form, improves the effect of water pumping gas production
Rate.

Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, and embodiment of the present utility model includes
But it is not limited to the following example.
Embodiment 1
As it is shown in figure 1, a kind of underground vortex instrument, including the fishing head 1 being from top to bottom sequentially connected with, stream device 2, water conservancy diversion
Cylinder 3, baffle ring 4；The described device outer wall that streams is provided with the helical blade 5 of projection；Groove, and this groove is had on described helical blade
The two ends of helical blade are extended to along helical blade；Expansion piece 6 it is provided with in described groove；Described expansion piece is in the shape of a spiral, and swollen
The external diameter of swollen part is equal to the external diameter of helical blade.
What deserves to be explained is, this utility model mainly arranges groove on helical blade, and groove is as spiral
Blade arranges (helical blade total length arranges groove), so groove is the most twist.When actually used, this utility model stretches into
After oil pipe, meeting water due to expansion piece can expand, and this makes it possible to make expansion piece be fitted in tube inner wall closely, makes to pass through eddy current
The fluid of instrument is completely by spiral type cavity, to change its fluidised form, improves the efficiency of water pumping gas production.External diameter due to expansion piece
Equal to the external diameter of helical blade, so can easily this utility model be encased in oil pipe, and when expansion piece expands, energy
Fit with tube inner wall the most easily.If expansion piece external diameter is less than helical blade external diameter, the expanded thickness of such expansion piece is inevitable
Need to increase, so can fit tightly with tube inner wall.If expansion piece external diameter is more than helical blade external diameter, by this practicality
Novel when putting into oil pipe, expansion piece can hinder this utility model to move.
Preferred as one, the external diameter of described helical blade is than pipe aperture little 6～8mm.By above-mentioned restriction, it is possible to really
The utility model that breaks even puts into oil pipe easily, and after expansion piece expands, it is possible to fit tightly with tube inner wall, the closeest
Envelope.
In order to preferably realize this utility model, described groove is arranged at the centre of the lobe of helical blade.Logical
Cross the centre that groove is arranged at helical blade, easy to process, and it is able to ensure that the stability of sealing.
Specifically, described expansion piece is to be made by the material of water-swellable.
Embodiment 2
As shown in Figure 2,3, the present embodiment is with the difference of embodiment 1, and described groove both sides are additionally provided with draw-in groove 7；Described
Expansion piece both sides are provided with the boss 8 snapped in draw-in groove.Specifically, draw-in groove is positioned at the middle part on groove side limit, and boss also is located at expanding
The middle part of part side；By arranging draw-in groove at groove both sides (namely on helical blade), it is possible to boss is snapped in wherein, thus
Expansion piece is fixed on groove, it is to avoid it departs from groove.
Embodiment 3
As shown in Figure 4,5, the present embodiment is with the difference of embodiment 1, and described groove both sides are additionally provided with draw-in groove 7；Described
Expansion piece both sides are provided with the boss 8 snapped in draw-in groove.Specifically, draw-in groove is positioned at the bottom on groove side limit, and boss also is located at expanding
The bottom of part side；By arranging draw-in groove at groove both sides (namely on helical blade), it is possible to boss is snapped in wherein, thus
Expansion piece is fixed on groove, it is to avoid it departs from groove.
According to above-described embodiment, this utility model just can be realized well.What deserves to be explained is, design based on said structure
On the premise of, for solving same technical problem, even if some made on this utility model are without substantial change or profit
Color, the essence of the technical scheme used is still as this utility model, therefore it should also be as at protection model of the present utility model
In enclosing.
