The deep target strata K1q, J3k and J2t in the Hutubi area have large-scale reservoirs and abundant oil and gas resources, but the traditional rock physics modeling of porous media cannot effectively distinguish oil and gas desserts from mudstones. Based on the systematic analysis of the logging curve characteristics of the target section, the shear wave velocity is corrected by the differential equivalent medium rock physics model, and the VPVSC and PIMP curves are restored by the Gassman equation fluid replacement, which highlights the sweet spot reservoir and mudstone discrimination. The linear sliding theory is introduced to establish the rock physics model of fractured reservoirs in dual-porosity media. The differential equivalent medium rock physics model for primary pores and the linear sliding model for anisotropic secondary fractures are organically integrated to realize the anisotropic medium rock physics modeling of the pore-fracture reservoir in the Hu 1-Hu 6 well area, and the rock physics plate is constructed. Combined with the anisotropic inversion of pre-stack OVT domain seismic data, the dominant reservoirs are effectively predicted. This paper has formed a complete set of deep fracture prediction method and technical processes, that provide a reference for the exploration and development of deep targets in similar exploration areas.
