Algal reef dolomite discrimination and physical property analysis method based on three-dimensional tomography

The invention discloses an algal reef dolomite discrimination and physical property analysis method based on three-dimensional tomography, which comprises the following steps of: firstly, discriminating species of plant algal reefs to ensure comprehensive analysis and observation; then scanning and analyzing the biological type, distribution characteristics and structural construction in the rock core based on a three-dimensional tomography CT scanner, confirming that the biological fossil forms a biological skeleton, and describing the characteristics of the biological skeleton; determining skeleton structure construction according to analysis and classification, and naming rock types according to skeleton structure construction characteristics; secondly, three-dimensional tomography is used for visually scanning data in a perspective mode, and a CT image is reconstructed; and finally, carrying out analysis processing by utilizing scanning data, calculating physical property parameters such as porosity and s
