| description | The invention discloses a volcanic rock geological gas content detection method, and the method comprises the steps: obtaining the post-stack seismic section data of an object geological region, and carrying out the strong axis removal of the post-stack seismic section data; carrying out continuous wavelet transform processing on the post-stack seismic section data subjected to strong axis removal processing; extracting the centroid frequency at each moment; obtaining a corresponding effective frequency for the integral energy of the centroid frequency according to a set quantity; and the gas-containing position corresponding to the effective frequency is obtained by utilizing the fluid fluidity. According to the method, on the basis of the post-stack seismic section data, the post-stack seismic section data subjected to strong axis removal processing is subjected to high-precision time-frequency analysis processing such as continuous wavelet transform, centroid frequency extraction, effective frequency acqui |
