The water mixing type polymer dispersing and dissolving device has the beneficial effects that the structure is simple, the cost is low, the polymer dry powder can be fully mixed, the phenomenon of blockage of the device is not easy to occur, the 'fish eye shape' cannot be generated, and the polymer dry powder mixing effect is good.
Description
Technical field
The utility model relates to a kind of tertiary oil recovery ground corollary equipment polymer injection device, especially relates to the water-mixed polymer dispersed dissolver in a kind of polymer injection device.
Background technology
Along with deepening continuously of oil field prospecting exploitation, many old fileds are through the exploitation of primary oil recoveries, secondary oil recovery, face that stable yields raising the output difficulty increases, the secondary oil recovery effect worse and worse, improve difficulties such as the recovery ratio difficulty strengthens year by year.To an above-mentioned difficult problem, the tertiary oil recovery technology of taking as the leading factor with polymer displacement of reservoir oil tech is one of important technology that the oil extraction later stage improves recovery ratio.Polymer injection tertiary oil recovery ground corollary equipment mainly comprises dissolving unit, feeding unit, slaking unit, injects the unit; And dissolving unit, feeding unit, slaking unit, injection unit are communicated with successively, and the effect of wherein dissolving the unit is with being delivered to the injection unit behind polymer dry powder and the water preliminarily solubilised.
At present; Polymer dissolution device (seeing accompanying drawing 1) adopts air blast dry powder hoisting way; Mainly comprise the dry powder delivery assembly, mix assembly, back with water inlet line 7, mixed liquor export pipeline 8, back with water inlet line 7 is equipped with gate valve 6, flowmeter 5, control valve 4 successively on pipeline, and is communicated with blender 2; Be installed on the mixed liquor export pipeline 8 of blending tank 12 lower ends gate valve 11, rear pump 10, stop valve 9 are installed successively; One end of injector 14 is communicated with air blast 15; After polymer dry powder in the storage bin hopper 1 gets into injector 14 through blanking meter 13; Under the effect of air blast 15, get into blender 2 through pipeline, with back with water inlet line 7 come water together to get into blender 2 tentatively to mix, mixed liquor gets in the blending tank 12; Through after the stirring of mixer 3, be delivered to the slaking unit through mixed liquor export pipeline 8.
Adopt high, the easy obstruction of polymer dissolution apparatus structure complicacy, cost, the polymer dry powder mixed effect of air blast dry powder hoisting way bad, have " flake ", the injection effect of impact polymer.
The utility model content
Bad in order to overcome the complex structure, cost height, easy obstruction, the polymer dry powder mixed effect that have the polymer dissolution device existence of adopting air blast dry powder hoisting way now; Be prone to produce " flake "; The deficiency of the injection effect of impact polymer, the utility model provide a kind of water-mixed polymer dispersed dissolver.
The utility model solves the technical scheme that its technical problem adopted: water-mixed polymer dispersed dissolver; Comprise storage bin hopper, blanking meter, injector, back with water inlet line, mixed liquor export pipeline; Polymer dry powder in the storage bin hopper gets into injector through the blanking meter that is installed in the storage bin hopper below; Injector is the Wen Qiuli injector, and the entrance point of injector is communicated with back with water inlet line, and the port of export of injector is communicated with the mixed liquor export pipeline.Flowmeter, control valve, Pressure gauge are installed on the back with water inlet line successively; Rear pump, stop valve, gate valve are installed on the mixed liquor export pipeline successively.
The beneficial effect of the utility model is, simple in structure, cost is low, and polymer dry powder can access abundant mixing, is difficult for the generating means clogging, does not produce " flake ", and mixed with polymers is effective.
