Abstract
Characterized by thin layers and low-angle fractures, the tight sandstone reservoir in the Chongzhou area of the Sichuan Basin can not be simulated by forward modelling methods based on Zoeppritz equations or their approximations. To address this problem, we propose a fast anisotropic reflectivity method for simulating the tight sandstone reservoir under the condition when it is equivalent to vertically transversely isotropic media. The fast anisotropic reflectivity method proposed here can compute the full-wave responses, including the reflection, transmission, mode conversion, and internal multiples. After the result comes out, we compare it with the outcome of another existing method to verify the correctness. Moreover, we also apply this method to the field data and compare it with the simulation results based on the Zoeppritz equation.
