Rock physics model provides an essential theoretical tool to quantify the impacts of reservoir physical parameters (porosity, water saturation, etc.) on seismic elastic properties including P- wave velocity and S-wave velocity. As a core module for deriving physical properties through joint well-seismic inversion, rock physics modeling accuracy directly determines the reliability of reservoir property prediction. Simultaneous characterization of pores and oriented fractures is required to refine modeling precision, yet the resulting excessive model parameters severely limit applications to field seismic data. To address the critical issue of applying pore and fracture anisotropic rock physics models to azimuthal seismic interpretation, this work decouples pores and oriented fractures during modeling. We postulate that pore variations control the model’s isotropic elastic properties, whereas oriented fracture characteristics dominate anisotropic parameters. Well-log data are utilized to invert key modeling parameters (matrix mineral elastic moduli, fracture porosity, etc.) for model correction. The corrected rock physics model is further coupled with the Rüger reflectivity equation to analyze how porosity and fracture azimuth alter seismic reflection coefficients and synthetic seismic records. The presented anisotropic rock physics correction method via parameter inversion greatly elevates modeling accuracy. Rock-physics-based analysis of azimuthal seismic reflection shows promising prospects for widespread use in fractured reservoir characterization.
