Research on the seismic resolution of thin beds based on the forward modeling

摘要：

In geophysics exploration area,research on the seismic resolution and reflection characteristic of thin beds is valuable.Based on the forward modeling technique and the practical data,we build two models,they are low amplitude structure anticline reservoir sand body model and layer pinch out model.We analyzed the seismic reflection wave of geological model in time and frequency domain respectively.The paper point out the 35Hz,the optimum exciting dominant frequency,improved the resolution and the prediction accuracy.The amplitude,frequency and impedance attributes are sensitive parameters in prediction.The results that can reduce multiple interpretations are valuable for low amplitude structure prediction.
