Description
Technical field
The utility model relates to and is applicable to Treatment Techniques of Extracted Water from Crude Oil Production field, especially oil field and petrochemical industry difficult degradation technical field of sewage.
Background technology
Along with domestic Ge great main force oil field enters the middle and later periods of oil production successively, Produced Liquid moisture ratio has reached 70%～95%, need association sewage quantity to be processed to continue to increase, simultaneously for maintaining the stable yields increasing the storage in oil field, tertiary oil recovery Technology large-scale application, make polymkeric substance in extraction sewage, the hard-degraded substance content such as surfactant increase year by year, from east China tertiary oil production in oil field production fluid present situation, unit drives in individual well production fluid, polymer quality concentration reaches 100～300 mg/L, in binary combination flooding individual well production fluid, polymer quality concentration has reaches 1000 mg/L, make to become containing the oily(waste)water of polymkeric substance a kind of profit system of complexity, oily(waste)water viscosity increases, oily water separation speed slows down, affected the normal processing of oilfield sewage, when serious, can cause processing rear oil content of wastewater and suspension content severe overweight.Therefore, work out the treatment technology of suitable tertiary oil recovery production fluid extremely urgent.
Outside tertiary oil recovery sewage, disposing polluted water in oil technical field remains to be returned discharge opeing, the unstable high-turbidity sewage of system etc. at system sewage backwash water, fracture acidizing and is difficult to process, be difficult to biodegradable sewage.
High-level oxidation technology, take that to produce the hydroxyl radical free radical with strong oxidation capacity be feature, under the reaction conditionss such as High Temperature High Pressure, electricity, sound, photoirradiation, catalyzer, makes macromole hardly degraded organic substance be oxidized to low toxicity or nontoxic small-molecule substance.Generally be divided into photochemical oxidation, Catalytic Wet Oxidation, sonochemical oxidation, ozone oxidation, electrochemical oxidation, Fenton oxidation etc.
In summary it can be seen, China's ozonization method is processed oilfield sewage still in conceptual phase at present, to the research of disposing polluted water in oil technology, be mainly indoor, much directly to use ready-made instrument to test or apply, the pollutent that especially cannot may occur in following production process oilfield sewage, the oxide treatment effect of high density pollution material is carried out quantitative research, thereby also cannot form integral body, the ozonization method of system is processed the method for difficult degradation oilfield sewage and the judgement of the integral body of technique, cannot have and provide effective technique to on-the-spot industrialization design, operating parameter, rig-site utilization is not had to practicable directive significance.
Especially at high-concentration waste water, impact in sewage field experiment containing the poly-high densitys such as discharge opeing of returning containing surfactant oil extraction-generated waste water, fracture acidizing, lack effective high density pollution thing and prepare continuously dosing system, can only carry out test to existing sewage, thereby test-results is perspective not strong, testing data has larger limitation.
Utility model content
The utility model object is to develop a kind of continuous, stable, molten throwing system of interpolation pollution substance gageable oilfield sewage test in place pollutent.
The utility model comprises that high density pollution thing quantitatively adds tank, simulating pollution thing mixing tank, sedimentation oil separation tank, ozonize retort and air water mixing jet device, high density pollution thing quantitatively adds the top that tank is connected to simulating pollution thing mixing tank, the discharge port of simulating pollution thing mixing tank is connected with an opening for feed of sedimentation oil separation tank by pipeline, on the pipeline between simulating pollution thing mixing tank and sedimentation oil separation tank, be connected in series peristaltic pump and under meter, another opening for feed of sedimentation oil separation tank connects water-in, liquid outlet at sedimentation oil separation tank is connected with the fluid inlet of ozonize retort by pipeline, liquid outlet in ozonize retort is connected with the fluid inlet of mixing wastewater with air ejector with water mixing topping-up pump by ozone, the liquid outlet of mixing wastewater with air ejector is connected to the inner chamber of ozonize retort, liquid outlet in the discharge port of simulating pollution thing mixing tank, the liquid outlet of sedimentation oil separation tank and ozonize retort arranges respectively sampling valve.
By the polymkeric substance using in recovering the oil, surfactant, the melon glue using in pressure break, the acid solution of using in acidifying, the volume expansion grain using in profile control, the simulating pollution things such as polymeric crosslinker add high density pollution thing quantitatively to add in tank, and control dosage and add speed, the degree requirement that the pollutent of preparation need to be sheared as required, simulating pollution thing mixing tank is fully mixed simulating pollution thing, after swelling, open the outlet valve of simulating pollution thing mixing tank, and according to the continuous data of under meter, adjust aperture that pollutent adds pump early gate and realize pollutent and quantitatively accurately add continuously, the sampling valve sampling observation of discharge port or the variation of test mixing front and back parameters from simulating pollution thing mixing tank, recycling is as sedimentation oil separation tank, the sewage disposal testing apparatus of ozonize retort etc., by each thief hole, sample respectively and observe and test, realize the judgement of mixing and reaction effect, with realize on-the-spot sewage treatment process preferably and testing apparatus operating parameter preferably.
The beneficial effects of the utility model are:
1, high density pollution thing can quantitative automaticly add stirring swelling, thereby steadily reliable.
2, stirring swelling scheme can select, according to the swelling requirement of simulating pollution thing, there are two kinds to stir scheme optimization, a kind ofly by assembly, regulate and increase solution shear intensity, a kind of by reducing assembly and adjusting mixing position, reduce the object of the intensity of shearing, reach the requirement of simulating pollution thing.
3, mixing effect is convenient to observe and decide, sampling and testing.
4, the simulating pollution material preparing can be realized continuously and adding, and it adds process, and to add dosage measurable.
Totally see, the quantitative preparation that the utility model can solve required pollutent in test in place with quantitatively add and test, guarantee test in place especially as containing poly-waste water, containing surfactant waste water, fracture acidizing, return the needs of the used water difficult to degradate field experiments such as draining.
In addition, the discharge port setting that the utility model also quantitatively adds tank at described high density pollution thing adds by-pass valve control, to utilize easily the aperture size of by-pass valve control to realize adding of quantitative contamination.
Above simulating pollution thing mixing tank, by erecting frame, agitator motor is set, the output terminal connection rotating shaft of agitator motor, the lower end of rotating shaft is inserted into the inner chamber of simulating pollution thing mixing tank, in the rotating shaft of simulating pollution thing mixing tank inner chamber, connects blade-rotating.
By erecting frame can be selectively in the central position of simulating pollution thing mixing tank or the fixing agitator of eccentric position.Little a lot of to the shearing meeting of pollutent at central position agitator, be placed on eccentric position place and stir, much larger to the shearing of pollutent, according to actual pollutent preparation, need to make different positions and place selection.
The utility model also arranges draw-in groove at the inwall of simulating pollution thing mixing tank, connects blocker plate on draw-in groove.If pollutent be need shearing treatment blocker plate is just installed, to improve shear effect; Otherwise remove blocker plate, reduce to shear Pollutant effects.
