Abstract

Summary

Reservoir fluid content can cause anomalous attenuation on seismic reflection. The diffusion-viscous theory can properly explain the attenuation. We propose a new numerical simulation method based on a diffusion-viscous wave equation (DVED), which has the advantages of phase-shift modeling but can still accommodate the lateral variation of velocity, diffusion and viscosity. We design a channel model, and use the DVED based method and traditional acoustic wave equation (AWE) based method respectively to simulate the frequency-dependent attenuation and the corresponding seismic reflection of fluid-saturated reservoir. The modeling and migration results indicate that the method is accurate and can well simulate the frequency-dependent attenuation appears below the fluid-saturated reservoirs.
