Review on methods of paleo-geomorphologic restoration

Paleo-geomorphologic configuration controls the sedimentary facies types and distribution, thus controlling the source-reservoir-cap assemblage of oil and gas reservoirs. Therefore, the accurate restoration of paleo-geomorphologic donfiguraion is of great significance for oil and gas exploration. On the basis of previous studies, by using the high-resolution sequence stratigraphy method, dual interface method,stripping and filling method, tectonic sedimentation simulation method and micro-amplitude paleogeomorphology calculation method, the methods of paleo-geomorphologic restoration were summarized.The results show that the dual interface method can be used to restore the paleogeomorphology in small areas, the tectonic sedimentation simulation method should be used in the areas with strong tectonic movement, while for some microstructural areas, the micro-amplitude paleogeomorphology calculation method can more accurately restore the paleo-geomorphologic configuration.
