  • Analysis method, system and storage media of lithological and oil and gas containing properties of reservoirs
    Publication number: 20220221614
    Abstract: The present invention discloses an analysis method, system and storage medium of lithology and oil and gas containing properties of reservoirs, by getting spectral structure modes of logging signals of different lithological bands and different oil and gas containing strata with CWTFT algorithms from frequency spectral structural relationships between different chords in music by analogy; summarizing features of spectral structure modes of same lithology in different wells, and getting a spectral change law of rocks, and identifying lithology of unknown rocks; and analyzing characteristics of reservoirs from identified lithology, finding and comparing spectral change characteristics of oil and gas strata in different wells to predict oil and gas reservoirs.
