Abstract：Intuitive understanding of basin characteristics such as early paleostructure, paleoenvironment and paleocurrent could be got based
on paleogeomorphy restoring prototype basins, laying solid basis for further oil and gas exploration. Taking Wulanhua sag as an example, this
paper analyzed the structural characteristics of Mesozoic residual sags in Erlian Basin, combined multiple paleogeomorphic restoring methods
including the geophysical method, the residual thickness method, and sequence stratigraphic method, used 3D visualization technique as a
medium, and truly refl ected the structural development history characteristics of the sag. Paleogeomorphic restoring shows that Wulanhua
sag took shape during the sedimentary stage of Early Cretaceous Aershan Formation; the sedimentary stage of Tenggeer Formation is the
expansion stage of fault depression; lacustrine basin shrank and structure reversed during the sedimentary stage of Saihantala Formation, which
as a whole exhibited the characteristics that source rocks were thick at early stage and eroded at late stage.
