Disclosed is a method for evaluating a shale gas reservoir and seeking a desert area, comprising the following steps: drilling core columns in different directions, measuring dynamic and static parameters of a saturated core column to obtain a conversion relational expression of dynamic and static elastic modulus, physically simulating anisotropic rocks, and calculating and intersecting elastic parameters; according to the intersection result, obtaining a corresponding correlation between a sensitive elastic parameter or a combination of sensitive elastic parameters and parameters of a shale gas desert area, and solving and predicting the parameters or combination of parameters of the shale gas desert area; correcting log data, and acquiring an optimal logging curve; employing a multi-mineral analysis method and a core test analysis method to obtain models, and serializing the obtained models; inverting three-dimensional high-resolution post-stack earthquake data; and integrating various acquired favourable parameters of the shale gas reservoir in combination with an accurate burial depth, thickness, occurrence and plane distribution of the shale gas reservoir to obtain a gas containing prospect of the shale gas reservoir and to circle the desert area for shale gas exploitation and development. |
