Abstract：It is necessary to fully understand stratigraphic structure before isochronal stratigraphic correlation and reservoir characterization.For the third member of the Yanchang Formation in Heshui,Ordos Basin,we use seismic forward modeling to investigate its configuration.In view of clinoform seismic reflections,we design three conceptual models to describe the stratigraphic structure.After forward modeling,we compare synthetic reflections with observed reflections and conclude that two models are feasible in this prospect.In accordance with log responses,one model is finally determined to best describe the stratigraphic structure in this prospect.This method may also apply to other prospects with similar geologic setting.
