///Standardization is important for the future research on sequence stratigraphy. The framework includes genetic modeling, establishing standardization and application of industrialization. The workflow emphasizes defining the genetic type of sedimentation and the bounding surfaces. Using the technique in the sequence-lithofacies paleographic research of the upper Triassic Xujiahe Formation in Sichuan Basin, the Xujiahe Formation could be divided into five third-order sequences. Based on sequence-paleogeographic research, the second, fourth, and sixth member of the Xujiahe Formation are defined to be the main reservoir, and the interbedded mudstones could be the source rock. The first, third, and fifth member of the Xujiahe Formation are defined to be the main source rocks; the delta sandstone with lesser scale along basin margin is a significant reservoir too.
