Abstract
The utility model relates to a gravel packing sand-proof tool which comprises a rushing pipe, a centre pipe and a wire wrapped liner. A turbine is provided on the rushing pipe. The utility model breaks the fashion of existing technique using gravel packing free settlement, which makes gravel collocate tightly under the revolving turbulent-flow conditions to reach a good effect.
Description
One, technical field
The utility model relates to the sand control construction tool, particularly a kind of wire-wrapped screen gravel filling sand prevention instrument that is used for.
Two, background technology
At present, in the employed kit 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, replenishes the gravel of filling out and relies on the gravity of himself to be the natural sedimentation state, thereby exist institute's gravel of filling out loose, arrange loose, shortcoming or deficiencies such as sand controlling result difference.
Three, summary of the invention
The purpose of this utility model provides a kind of gravel filling sand prevention instrument, it can overcome or avoid the shortcoming or the deficiency that exist in the above-mentioned prior art, it can stir effectively to mortar, produce strong turbulent flow, the gravel of accumulation is rearranged, it is closely knit to reach filling, the significant purpose of sand controlling result.
Gravel filling sand prevention instrument described in the utility model comprises washing pipe, central tube and wire-wrapped screen, and a turbine device is installed on washing pipe.
Wherein, described turbine device is a blade-carrying tubular body.Blade on the described turbine device is 0 °～90 ° rotation arrangement architecture.Described turbine device is enclosed within the external surface of washing pipe, and is with it and is slidingly matched.Described turbine device also can be its blade interior and exterior angle opposite configuration, is suspended on the washing pipe by hanging angle apparatus, is with washing pipe to be slidingly matched.
The utility model compared with prior art has following advantage:
Broken the mode of prior art gravel pack free settling, gravel is closely arranged under the rotation turbulent condition, filling is closely knit, and effect is remarkable.
Four, description of drawings
Fig. 1 is first example structure figure of the present utility model;
Fig. 2 is another example structure figure of the present utility model.
Five, the specific embodiment
Consult Fig. 1-Fig. 2, a kind of gravel filling sand prevention instrument comprises washing pipe 1, central tube 2 and wire-wrapped screen 3, and a turbine device 6 is installed on washing pipe 1.
Turbine device 6 is a blade-carrying tubular body.Blade 4 on the turbine device 6 is 0 °～90 ° rotation arrangement architecture.Turbine device 6 is enclosed within the external surface of washing pipe 1, and is with it and is slidingly matched.Turbine device 6 also can be its blade 4 inner and exterior angle opposite configuration, is suspended on the washing pipe 1 by hanging angle apparatus 7, is with washing pipe to be slidingly matched.
Fluid in this structure washing pipe 1 is to its intra vane 4 generation effects, and therefore the liquid of washing pipe outside stream, can produce stronger turbulent phenomenon to the also generation effect of its outer leafs simultaneously, and stronger stirring gravel makes gravel filling sand prevention have more effectiveness.The utility model is lowered in the sleeve pipe 5 with kit.
Claims (5)
1, a kind of gravel filling sand prevention instrument comprises washing pipe, central tube and wire-wrapped screen, it is characterized in that installing on washing pipe a turbine device.
2, gravel filling sand prevention instrument according to claim 1 is characterized in that described turbine device is a blade-carrying tubular body.
