Three-dimensional quantitative prediction method and device for crustal stress, electronic equipment and medium

The invention discloses a three-dimensional quantitative prediction method and device for crustal stress, electronic equipment and a medium, and the prediction method comprises the steps: obtaining two-way horizontal crustal stress of a single well and parameters related to the crustal stress, and taking the two-way horizontal crustal stress and the parameters as training samples; based on a machine learning algorithm, constructing a single-well machine learning training model reflecting the mapping relation between the two-way horizontal ground stress and the parameters, and training the single-well machine learning training model; performing pre-stack inversion based on the pre-stack seismic data to obtain a three-dimensional data volume related to the crustal stress; and by using the trained single well machine learning training model, taking the three-dimensional data volume as input, and carrying out two-way horizontal crustal stress three-dimensional quantitative prediction. The method can solve the pro
