Summary: | The invention provides an ancient landform restoration method, and belongs to the technical field of oil exploration. The ancient landform restoration method comprises the following steps: acquiring a rock core sample; performing lithofacies analysis on the rock core sample, and determining the lithology type of each stratum; detecting the content of trace elements in the rock core sample; carrying out stratigraphic division; selecting a marker bed; determining an oxidation reduction environment of each stratum according to the content of the trace elements; determining the residual stratum thickness of each stratum according to the lithology type of each stratum, the sedimentary stratum thickness of each stratum and the oxidation-reduction environment; and recovering the ancient landform according to the residual stratum thickness of each stratum. The ancient landform is recovered through the thickness of the residual stratum of each stratum, so that oil-gas exploration is effectively guided.
