For Bohai metamorphic buried hill, with the characteristics of rapid vertical and horizontal velocity change and strong reservoir heterogeneity, the prediction of fracture reservoir plays a crucial role in the oilfield development. Conventional fracture prediction methods are difficult to accurately predict the buried hill fracture reservoir. A new pre-stack inversion method for high-angle fracture reservoir is proposed in this paper. The method firstly carries out texture analysis based on gray level co-occurrence matrix on the original seismic data, extracts the seismic high-angle reflection information reflecting the response of the fracture reservoir, and integrates it with the low-frequency model of conventional pre-stack inversion to construct a low-frequency model suitable for the strong heterogeneous reservoir in the buried hill of the Archean space, and then carries out fine pre-stack inversion. In this paper, the method is applied to the prediction of fracture reservoir in Bozhong 26-6 oilfield. The results show that the method can improve the inversion effect and the prediction accuracy of fractured reservoir in Bozhong 26-6 oilfield, and provide a reliable basis for the deployment of development wells in Bozhong 26-6 oilfield.
