As a preferred embodiment of the utility model, above-mentioned centerbody is a solid cylinder.
Advantageous effects brought by the utility model are as follows:
Compared with prior art, the utility model passes through oil inlet pipe, its internal centerbody and double helix blade phase interworking
It closes, when wet crude passes through double helix blade, due to being subject to centrifugal forces, the water of low viscosity is displaced to close to oil inlet pipe
The side of inner wall, highly viscous crude oil are gathered in the center of oil inlet pipe.Water is wrapped in oil and forms core annular flow, i.e. water at this time
Ring.Double helix blade is fixed between oil inlet pipe and centerbody by centerbody.Water ring is flowed up along oil inlet pipe, is substantially reduced
The resistance of flow process.Since oil inlet pipe is disposed vertically, grease is only by along the downward gravity of pipeline and tangential force, therefore
The water ring of formation is not easy bias, has preferable stability, to realize that water ring conveys highly viscous crude.
Casing is provided on the outside of oil inlet pipe, casing is preferably high strength casing, can be supported to oil inlet pipe, is enhanced
Its stability.
When carrying out conveying highly viscous crude using utility model device, underground overbottom pressure can not be utilized by external energy
Grease homogeneous flow is imported into oil pipe, using fixed double helix blade by water-oil separating, forms viscous crude in the center of oil inlet pipe, water
Ring greatly reduces the resistance in transmission process in the grease annular flow of oil inlet tube wall side, reduces the conveying energy consumption of pipeline.

Specific embodiment
The utility model proposes a kind of oil field well industrial water ring forming devices, in order to make the excellent of the utility model
Point, technical solution are clearer, clear, elaborate combined with specific embodiments below to the utility model.
As shown in Figure 1, a kind of oil field well industrial water ring forming device of the utility model, including oil inlet pipe 7, casing 3,
Double helix blade 5, centerbody 6, oil inlet pipe 7 is vertical distribution, so set, grease is only by the gravity downward along oil inlet pipe
And tangential force has preferable stability so that the water ring formed is not easy bias.The bottom of oil inlet pipe 7 is oil inlet 1, oil inlet
It is preferably threadedly coupled at mouth 1, convenient for being attached with external water source.Import notch 2 and outlet slot 4 are provided on casing,
Import notch 2 can perfectly be snapped into the outlet slot 4 of the preceding paragraph pipeline, and outlet slot 4 can perfectly be fastened on next
The import notch 2 of segment pipe, such design method had not only facilitated connection, but also had the advantages that good airproof performance, low manufacture cost.
