Abstract: The present paper deals with the relationship between reservoir sandstone distribution, regional tectonics and sedimentary background of the H63 reservoir sandstones from the Pinghu Oil and Gas Field in the eastern Zhejiang depression. The reservoir model presented in this study shows that the residual oil is dominantly concentrated in the beach bar sandstones at the uppermost part of the H63 reservoir sandstones due to highly heterogeneity of the beach bar sandstones in the study area.
