Based on the knowledge of the sedimentary and tectonic settings in the northeast of the Sichuan Basin, with the careful analysis of the sequence surfaces, facies section, the stacking pattern, well-logging curves and seismic sequence stratigraphy, and so on, there are 2 third-order sequences distinguished in the Feixianguan Formation in the northeast of the Sichuan Basin, both of which include the LST, TST and HST. Furthermore, using the theory of the sequence stratigraphy, by establishing the framework of the sequence stratigraphy of the Feixianguan Formation in the northeast of the Sichuan Basin, based on the analysis of the control factors of the sequence stratigraphy, the evolution model of the sequence stratigraphy of the Feixianguan Formation is established in the northeast of the Sichuan Basin.
