Abstract
The utility model relates to a swirling filling device, which comprises a wash pipe, a central pipe, and a wire wrapping screen, wherein the central pipe is mounted in the wire wrapping screen, the wash pipe is mounted in the central pipe, and a cyclone is mounted on the wash tube. The swirling filling device has the advantages of swirling, filling, leading placing sand to be compact, and improving sand prevention effect, which can be widely used in sand prevention technique in oil production.
Description
One, technical field
The utility model relates to oil exploitation sand control construction tool, particularly a kind of eddy flow device for filling.
Two, background technology
In the employed conventional tool of the on-the-spot wire-wrapped screen gravel filling sand prevention process in oil field, its washing pipe adopts the straight pipe type structure, the gravel that is filled with relies on the gravity of himself to be the natural sedimentation state, thereby there is shortcoming or deficiencies such as institute's gravel of filling out is loose, arrangement is loose, sand controlling result difference.
Three, summary of the invention
The purpose of this utility model provides a kind of eddy flow device for filling, it can overcome and avoid the shortcoming that exists in the above-mentioned prior art, effectively mortar is stirred, and produces strong eddy flow, the gravel of accumulation is rearranged, reach that filling is closely knit, the significant purpose of sand controlling result.
Eddy flow device for filling described in the utility model comprises washing pipe, central tube and wire-wrapped screen, and described central tube is installed in the wire-wrapped screen, and washing pipe is installed in the central tube, and a cyclone is installed on the described washing pipe.
Wherein, described cyclone is a blade-carrying tubular body.Be equipped with on the described cyclone and be the blade that 0 °～90 ° rotations are arranged.Described cyclone is sleeved on the external surface of washing pipe, and is with it and is slidingly matched.
The utility model has following advantage compared with prior art:
Broken the mode of prior art gravel pack free settling, gravel is closely arranged under the eddy flow state, filling is closely knit, and effect is remarkable.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Five, the specific embodiment
Consult accompanying drawing, a kind of eddy flow device for filling comprises washing pipe 1, central tube 2 and wire-wrapped screen 3, and central tube 2 is installed in the wire-wrapped screen 3, and washing pipe 1 is installed in the central tube 2, and a cyclone 4 is installed on the washing pipe 2.
Cyclone 4 is a blade-carrying tubular body.Be equipped with on the described cyclone and be the blade that 0 °～90 ° rotations are arranged.Cyclone 4 is sleeved on the external surface of washing pipe 1, and is with it and is slidingly matched.
