摘要: A novel nanofluid based on fluorescent carbon nanoparticles for enhanced oil recovery (EOR) was developed. Fluorescent prepared by a simple and rapid method were used as chemical agent EOR fluorescence imaging. Transmission electron microscope Fourier transform infrared spectrometer employed to observe the shape, size, surface components of nanoparticles. The could be instantly dispersed in water without any auxiliary equipment. showed excellent antitemperature, antisalinity, displacement, wettability alteration properties. (0.1 wt %) reduce oil–water interfacial tension 13.4 mN/m. core immersed significantly improved. intersection observed microscope. image demonstrated that had seeped into core. nanoparticle-...
