Using the data obtained from seismic, well log, and assaying, the research is conducted on sequence stratification and sedimentary facies of Taoyuan Formation, Yuanjiang Formation, Hanshou Formation, and Xinhekou Formation of Paleogene inYuanjiang sag in the Dongtinghu Basin.

The Paleogene in Yuanjiang sag of the Dongting basin occurs as a NE-trending quasi-dustpan-shaped sag being faulted in the southeast and onlapping in the northwest.
