Abstract：Sedimentary cycle is a result of the periodic occurrence of any depositional event. It is amaterial record of various depositional events in a certain time period. The key to stratigraphic sequence determination is to correctly demarcate sedimentary cycle. Common way to do so is to use logging data processed by Hilbert-Huang transformation (HHT). This method can only demarcate sedimentary cycle at well locations, but is usually restricted due to shortage of logging data. Therefore we propose sedimentary cycle demarcation based on seismic HHT. Empirical mode decomposition of seismic data is achieved by HHT, and strata spatial changes are obtained. We analyze 4 kinds of typical model of sedimentary cycle and their Hilbert spectrum. Application results on seismic data are consistent with that on logging data, which demonstrates the reliability of the proposed method.
