Abstract

Summary

A simple and new reflection coefficient equation should be expected as the foundation in the process of the effective reservoir and fluid prediction, when we turn attention of seismic exploration and interpretation gradually from 3D to 5D. Under the assumption of the attenuation transversely isotropic medium with vertical axis of symmetry medium model, we derive the linearized attenuation anisotropy reflection coefficient equation for fluid-bearing horizontally-fractured or horizontallylayered reservoir. The model is much closer to characterize the seismic wave propagation in the actual stratum than the assumption of the elastic isotropy or anisotropy medium. There are some inextricable relations between those parameters and the rock physical parameters that the porosity, fracture density and fluid. On this basis, we analyze the characteristics of reflection coefficient utilizing this equation. It provides an effective way for the seismic wave response analysis and the pre-stack seismic simultaneous inversion to predict the pores, fractures and fluids.
