摘要
In recent years,with continuous increase of high resolution seismic data,seismic stratigraphy is more and more closely connected with high-resolution sequence stratigraphy.According to the theory of sequence stratigraphy,the seismic data should firstly be reprocessed and reconstructed to build the isochronous stratigraphy framework.After building this isochronous seismic volume,all seismic sequence identification,seismic facies analysis and reservoir characterization should be carried out under this isochronous stratigraphic framework.
