摘 要:正It is important and profound to quantitatively study the relation between rheoiogy and microstructure for development of the microstructural mechanism of crude oil rheology and even for the waxy crude oil ***,due to the high complexity and irregularity of wax crystal morphology,quantitative characterization is hard to *** has hampered further study on the rbeology—microstructure relationship.A new approach combined the fractal geometry and the stereology theory is presented for quantifying the intricate wax crystal morphology and *** on the characterization,the effects of microstructures and oil composition on the waxy crude viscosities are analyzed quantitatively It further validates the previous qualitative research and enriches understanding into the microstructural mechanism of waxy crude oil rheology.
