Stress field characterization and evaluation is an important part of deep shale gas exploration and development, and is important in guiding the prediction of fracture crack direction, well network deployment, and horizontal well location deployment. Using the Longyi 1 subsection in Luzhou North District, Sichuan Basin, as an example; through indoor experiments, logging interpretation comparison, and stress field simulation prediction; we established the conversion relation equation of rock mechanics dynamic and static parameters, clarified the single well geostress characteristics, and completed the stress field perturbation analysis. This enabled us to realize the zoning portrayal of the stress field in the study area. The results of the study showed that:
