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. The present invention combines spectral response characteristics of logging curves of different lithology, improves accuracy and efficiency of lithology and reservoir features interpretation work and provides new theoretical support and practical experience for deep oil and gas reservoir prospection and development.
