Abstract

Abstract

Taking Jialingjiang formation in Puguang area as an example, with the fractures development law drawn in the area as a basis, the structural curvature method, S-wave wide azimuth anisotropy method and finite element method were used in fracture prediction, and the results and application conditions of each method were compared. The results show that the curvature method based on the geometry theory could be used to analyze the intensity of fracture development but not the azimuth. It fits in the area with fewer data, simple structure and folds. The S-wave wide azimuth anisotropy method is a preferred geophysics method, which could identify the azimuth and development density of the fracture; however, this method only fits in the area with dipping or high-angle fracture and requires a high quality of seismic data; The finite element method (FEM) could reappear the forming process of fractures in the way of forward and calculate the development intensity and azimuth, but it requires a good understanding of the fracture formation mechanism in the study area, and the accuracy of the prediction results depends on the precision of the model.
