Pre-Jurassic Paleogeomorphic Restoration Methods and Characteristics of the Central Ordos Basin

Licheng Xie, Guicheng Wang, Tiande Xi, Ni Cheng

Abstract

The pre-Jurassic paleogeomorphology has a significant impact on the distribution of oil reservoirs in the central Ordos Basin, particularly influencing the distribution of reservoirs in the Lower Jurassic Fuxian and Yanan formations. Accurate restoration of pre-Jurassic
paleogeomorphology is crucial for predicting reservoirs in the Yan 10 and Yan 9 layers. This study uses the primary method of imprint to
restore and characterize the pre-Jurassic paleogeomorphology of the Wuding area in detail. The paleogeomorphic units in the Wuding area include ancient rivers, slopes, highlands, and interfluvial hills. The restored paleogeomorphic features provide important geological evidence for
predicting the Lower Jurassic reservoirs.
