Based on numerical simulation analysis, the authors established the seismic response model and revealed that the bioherm forward modeling of seismic profiles and the bioherm model have good similarity. 3D seismic data and drilling data were employed to make seismic facies and sedimentary facies analysis and, as a result, the “platform marginal reef-phase” phase belt formed at the end of the Changxing Formation was recognized. On such a basis, the shape and distribution characteristics of the bioherm were inferred. The wave impedance inversion and logging curves were also studied.
