摘要
Based on drilling core, bore well, well logs and seismic data, the authors use the isochronous correlation to establish the Paleogene sequence stratigraphic framework in the Baiju sag, and discuss the relationship between source-reservoir-cap rock assemblages and third-order sequences. The low water level and later high water level system fields are the favorable place of reservoir development. The transgressive and early high water lelve system fields are the profitable place of source and cap rock formation. Three sets of source-reservoir-cap assemblages are formed among these fields, and the lower assemblage is the best one in Paleogene in the Baiju sag.
