中文摘要 | The concentration and size of suspended solids (SS) in the treated produced water beyond the criteria of injection water in Daqing oilfield have raised great concerns in recent years. The SS in produced water from water, polymer and alkali-surfactant-polymer (ASP) flooding were Successfully separated and characterized using some analytical techniques in this study. X-ray fluorescence (XRF), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR). and hearing method reveal that some organic Compounds besides crude oil were present in the SS samples, and polyacrylamide was found in the SS front polymer and ASP flooding. X-ray diffraction (XRD) shows some crystal inorganic substances such as SiO2, Fe2O3, Fe3O4, and BaSO4 in the SS samples. and XPS analysis indicated that several iron compounds with different valences were present in the three SS samples. The mean diameters of three SS samples were 22.89, 11.28 and 17.61 mu m respectively. Most importantly, the aggregates formed by the SS and oil droplets as well as the small SS adsorbed on thee Surface of oil droplets were observed using a microscope, indicating that the SS call be removed with Crude oil, and crude oil also contributes to the determination of the SS values.
