The study on two typical intra-cratonic basins, namely, Ordos Basin, China and Surat Basin, Australia indicates that the sequence stratigraphic infilling succession is correlated. The results show that intra-cratonic basin has unique stratigraphic infilling characteristics, such as 1) typical fining-upward lithology association successions with a sandstone-rich lower part and a mudstone-rich upper part; 2) asymmetrical base level cycle mainly composed of ascending half cycle; 3) sequence stratigraphy made up primarily of a lowstand system tract with multistorey stacked sandstones forming excellent reservoir quality, and little deposition of transgressive system tract and highstand systems tract with isolated sandstones within mud-dominated deposits forming medium or poor reservoir.
