Coherent ant fusion crack fine description method based on cepstrum analysis

The invention discloses a coherent ant fusion crack fine description method based on cepstrum analysis, and belongs to the field of oil and gas geophysical exploration. Fractures serve as important parameters for describing physical properties of oil and gas reservoir rocks, fine description of the fractures is of great significance for oil and gas geophysical exploration, especially for unconventional oil and gas reservoirs, the method is combined with a cepstrum analysis method, characteristics such as seismic event low-frequency enhancement effects are approximately and quantitatively represented by using cepstrum coefficients, and the method is suitable for the oil and gas geophysical exploration. The method is utilized to enhance the characteristics of the crack, a gradient structure tensor algorithm is combined to calculate coherence attributes and ant body attributes, an attribute proportion fusion analysis method is combined to fuse the calculated coherence attributes and ant body attributes to obtain
