摘要

Using the Automated Mineralogy (AM) technology based on the SEM-EDS plat-form, a series of image and mineralogical analyses can be carried out on samples, such as large-area high-resolution scene scanning, particle mineral analysis, specific mineral search and trace mineral search, etc. AM can meet the research needs of automated and rapid identification of mineral types, measurement of surface porosity, determination of mineral particle size, evaluation of the distribution characteristics of minerals and pores, and analysis of the distribution forms of elements. Form analysis, and other research needs. This paper focuses on the application of AM in three aspects of liquid-solid chemical reaction transport in reservoirs, including static and dynamic liquid-solid chemical reaction experiments as well as numerical simulation of liquid-solid chemical reaction transport, and draws three conclusions: (1) AM can help to reflect the real process of liquid-solid chemical reaction transport at the pore scale. In the process of oil and gas development, the non-homogeneity, pore fracture and mineral distribution of the reservoir will have an impact on the fluid-solid chemical reaction, and AM has obvious advantages in the study of the non-homogeneity, pore structure and mineral genesis of the reservoir.
