| Abstract: | The total salinity of produced water of station 42# of the ninth area in the 1st oil production factory in Zhongyuan oil field is high.The contents of SO42- and HCO3- of produced water of Wence well 215-5 are 1734mg/L and 2343mg/L respectively,the content of Ca2+ of Wen well 215-10 produced water of Wen well 215-10 is 12600mg/L; the contents of ions of Wen well 215-2 and Wence well 215-4 are complicated.The results of prediction and compatible experiment indicate that produced water from the station is mixed,it will format inorganic scales.The most component is CaSO4 hydrate by Xdiffraction analysis,as the result of the high content Ca2+ and SO42-in the mixed system and supersaturation CaSO4.The inhibitor CD-1 is optimized according to static state experiment which is suitable to the produced water from the station,and the scale inhibition effectiveness is good at pH 5～7.The inhibition rate is 97.2%,when the inhibitor CD-1 and adjuvant is at 200mg/L and 0.5‰ respectively,and it is not emulsified.The dynamic experiment shows that the inhibition rate is above 95% at the amount of inhibitor;field application shows that there is not format inorganic scale when produced water of 4 wells and 10 wells are gathered,which effectively solves the scaling problem at working sites. |
