Abstract: The sedimentary characteristics within the sequence stratigraphic framework of the Fourth Member of Xujiahe Formation in the middle area of western Sichuan depression were studied by using outcrops, seismic data, cores, logging and analytical testing. The characteristics showed that the Fourth Member of Xujiahe Formation is a three-order sequence,which is divided into lowstand, transgressive,and highstand system tracts according to the sequence boundary characteristics. The isochronous sequence stratigraphic framework was established and its internal sedimentary characteristics was clarified:Four types of sedimentary facies were developed, including the alluvial fan, braided river, braided river delta, and lacustrine. The characteristics of sedimentary facies distribution and vertical evolution in the sequence stratigraphic framework were also clarified. Horizontally, the alluvial fan, braided river, braided river delta, and lacustrine facies are developed in turn in the short axis provenance from the front of Longmen Mountain, while the braided river delta front deposition is mainly developed in the long axis provenance, and the short and long axis provenances are intersected in the area ranging from Hexingchang to Xinfan; Vertically, the lowstand system tract and highstand system tract are dominated by the braided river delta front, and the subaqueous distributary channel sand bodies are vertically superimposed and horizontally contiguous and widely distributed. The transgressive system tract is dominated by the shore-shallow lacustrine. Eventually, a sequence-sedimentary filling model was established. This study suggests that the subaqueous distributary channel sand bodies from the long axis provenance and the convergence areas of short and long axis provenance are quality reservoirs in the lowstand system tract and highstand system tract.

Key words: sequence stratigraphic framework, sedimentary facies, middle area of western Sichuan depression, Fourth Member of Xujiahe Formation
