Abstract: Instantaneous attributes including amplitude,instantaneous frequency, bandwidth, dominant frequency and decay rate are used to analyze thin interbeds.Several typical models were designed to get their seismic synthetic data and their instantaneous attributes were extracted individually. The results show that the synthetic seismic data were almost same to each other in the time domain. However, some of their instantaneous attributes may have obviously difference. As a result, multi-instantaneous attributes can be used to characterize the thin-layers and thin interbeds. Finally, a case study is presented in this paper,confirming their efficiency.
