  • Method and device for characterizing microbial carbonate pores, and server
    Patent number: 11566992
    Abstract: A method and device for characterizing microbial carbonate pores, and a server. Acquiring a user's detailed observational description of a profile of a microbial carbonate to be analyzed, and determining a full-diameter core sample on the microbial carbonate; performing pore characterization and a first pore test on the full-diameter core sample to determine a centimeter-scale pore parameter; determining a sampling position on the full-diameter core sample, and sampling on the full-diameter core sample to obtain a plunger sample; performing a second pore test on the plunger sample to determine a millimeter-scale pore parameter; determining a sampling position on the plunger sample according to the millimeter-scale pore parameter, and sampling on the plunger sample to obtain a scanning electron microscope (SEM) sample and a casting thin section sample; and performing a pore test on the SEM sample and the casting thin section sample to determine a micron-to-nanoscale pore parameter.
