Background technology
Tertiary oil production in oil field is the special equipment of tertiary oil production in oil field while carrying out the displacement of reservoir oil with polymer with polymer dispersed dissolver, it comprises ejector, dissolving tank, ejector is to utilize water inlet pipe to carry out water pressure, from ejector nozzle periphery, water is penetrated at a high speed, at nozzle, form parital vacuum around, produce negative pressure, dry powder is sucked to powder inlet pipe, be hybridly prepared into the solution of desired concn with high-velocity flow.The aqueous solutions of polymers being mixed with supercharging after the straight tube at ejector rear portion pumps into dissolving tank dissolving, curing by pump mixes backward oilbearing stratum and injects with water under high pressure.Owing to carrying gas in the aqueous solutions of polymers in process for preparation, aqueous solutions of polymers can affect the volumetric efficiency of injection pump by the fashionable gas that it carries of infusion, then affects concentration and the injection allocation amount of injection liquid.Former use device without degasser, is just directly connected with the import of dissolving tank by ejector rear end straight tube between ejector, dissolving tank.When the aqueous solutions of polymers being mixed with enters dissolving tank by straight tube, while being injected to oilbearing stratum by dissolving tank discharge again, because nothing in this system removes gas device, in aqueous solutions of polymers, entrained gas can only inject undergroundly thereupon, and its oil displacement efficiency of polymer that makes to inject oilbearing stratum is affected and affects the produced quantity of crude oil.
Summary of the invention
The purpose of this utility model is to provide a kind of tertiary oil production in oil field polymer dispersed dissolver, solve former with device without degasser, in aqueous solutions of polymers, entrained gas injects undergroundly thereupon, affects the problem of oil displacement efficiency.
The utility model is achieved through the following technical solutions: tertiary oil production in oil field polymer dispersed dissolver, comprises ejector and dissolving tank; Degassing tank is also housed between described ejector and dissolving tank, degassing tank is divided into segregation section, degassed shunting section and rectification section from top to bottom, wherein, segregation section and degassed shunting section are the helix tube being coiled in degassing tank, and on the helix tube inwall of degassed shunting section, have hole, vane type stainless steel helices is housed in rectification section; On degassing tank, have gas-liquid import, there is gas vent on top, and liquid outlet is arranged at bottom, and the helix tube of gas-liquid import and segregation section communicates, and gas-liquid import connects ejector, liquid outlet connection dissolving tank.
Further, described helix tube is flat square tube.
Further, in the helix tube end of described degassed shunting section, be laterally provided with dividing plate.
Adopt the good effect of technique scheme: the utility model increases degassing tank between ejector and dissolving tank, rational in infrastructure, separation factor can reach 20-35g, separated degasifying effect is good, preferably resolve the former device of using without degasser, in aqueous solutions of polymers, entrained gas injects undergroundly thereupon, and the problem of the polymer solution oil displacement efficiency that impact is injected, has improved the produced quantity of crude oil greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing of degassing tank in Fig. 1.
In figure, 1 ejector, 2 dissolving tanks, 3 degassing tanks, 4 helix tubes, 5 holes, 6 gas-liquid imports, 7 gas vents, 8 liquid outlets, 9 dividing plates.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the enlarged drawing of degassing tank in Fig. 1, and as shown in the figure, tertiary oil production in oil field polymer dispersed dissolver, comprises ejector 1 and dissolving tank 2.Between described ejector 1 and dissolving tank 2, degassing tank 3 is also housed, degassing tank 3 is divided into segregation section, degassed shunting section and rectification section from top to bottom, wherein, segregation section and degassed shunting section are the helix tube 4 being coiled in degassing tank 3, and on helix tube 4 inwalls of degassed shunting section, have hole 5, vane type stainless steel helices is housed in rectification section.The effect of degassing tank inner helix pipe is that the high polymer aqueous solution to mixing carries out aqueous vapor separation, import gas-liquid at a high speed utilizes hypergravity to realize better degasifying effect, under the effect of centrifugal force, the aqueous solutions of polymers that density is large is tending towards helix tube lateral wall, the gas that density is little is tending towards helix tube madial wall, and separation factor can reach 20-35g.The high polymer aqueous solution enters degassed shunting section after segregation section reaches certain separating effect, isolated gas is discharged by the hole on helix tube inwall, reduced the pressure in pipeline, be conducive to gas-liquid separation, avoided causing splash simultaneously when lower cavity is separated.The high polymer aqueous solution after degassed enters rectification section, and vane type stainless steel helices is housed in rectification section can avoid fluid to enter the still state in High Rotation Speed of rear end swiftly flowing liquid reduction of speed, the accident such as cause excessive tank, find time.Vane type stainless steel helices can allow liquid retain certain flow velocity, keeps certain rotation after making fluid enter dissolving tank.On degassing tank 3, have gas-liquid import 6, there is gas vent 7 on top, and liquid outlet 8 is arranged at bottom, and the helix tube 4 of gas-liquid import 6 and segregation section communicates, and gas-liquid import 6 connects ejector 1, liquid outlet 8 connection dissolving tanks 2.The gas that discharge in hole from helix tube inwall enters the cavity in helix tube, then from the outlet of degassing tank top gas, discharges, and the high polymer aqueous solution after degassed flows out and enters dissolving tank from the liquid outlet of degassing tank bottom.
In order to reach better separating effect, described helix tube 4 is flat square tube, specifically sees the place of broken section shown in Fig. 2, because under equal cross-sectional area condition, flat square tube more can shorten the flowing time of fluid than pipe, and within a short period of time is by gas-liquid separation.
Further, in helix tube 4 ends of described degassed shunting section, be laterally provided with dividing plate 9, specifically see the place of broken section shown in Fig. 2.Because dividing plate has certain length, and helix tube is that coiling is descending, therefore by dividing plate, one fluid streams is divided into secondary air body, secondary air body along helix tube rotation downwards, be 180 ° of distributions, distribute uniformly and enter next stream section, then through liquid outlet, enter dissolving tank.
The utility model increases degassing tank between ejector and dissolving tank, rational in infrastructure, separation factor can reach 20-35g, separated degasifying effect is good, preferably resolve the former device of using without degasser, in aqueous solutions of polymers, entrained gas injects undergroundly thereupon, and the problem of the polymer solution oil displacement efficiency that impact is injected, has improved the produced quantity of crude oil greatly.
