The invention belongs to the technical field of oil and gas field exploration and development, and discloses a fractured-vuggy reservoir ground stress prediction method and system based on discrete elements and finite elements. And taking the obtained boundary stress direction and size as boundary conditions, and combining with a pre-constructed fusion model to obtain the three-dimensional stress of the research area, thereby completing the fracture-vuggy reservoir crustal stress prediction process. The construction process of the fusion model comprises the steps that firstly, a discrete fracture network model and a geomechanical grid model are established, then the discrete fracture network model and the geomechanical grid model are fused, after fusion, three-dimensional heterogeneous parameters are given to the fusion model, and the construction process of the fusion model is completed. The method can accurately and efficiently simulate the three-dimensional distribution rule of the current stress field of the fracture-vug type reservoir, and is of great significance to oil-gas exploration and development.
