The western margin of Ordos Basin is located at the junction of different blocks, and the structural deformation has the characteristics of multi-stage, multi-attribute and multi-scale. In recent years, although some achievements have been made in the exploration of oil and gas risks in the western margin of the basin, no major breakthrough has been made due to the complex geological structure. In this paper, based on the three high-precision two-dimensional grid lines newly processed in the southern section of the western margin of the Ordos Basin, combined with regional geological data, drilling data and field geological survey, the seismic geological profile is constructed, and the 2D-Move software is used to quantitatively analyze the profile after fine resolution. Inversion recovery and forward modeling. The research shows that: (1) The structural framework of the southern section of the western Ordos Basin was essentially finalized during the Yanshanian. Its structural characteristics transition from fold deformation controlled by a composite structural wedge in the south to basement-involved imbricate thrust structures controlled by several major thrust faults in the north. (2) The G202203 profile traversing the Shajingzi area in the northern part of the southern section of the western Ordos Basin has a current length of 74.86 km. After fault displacement removal and stratigraphic flattening, the profile length is restored to 91.19 km. Calculations indicate a cumulative stratigraphic shortening of 16.33 km, resulting in a tectonic shortening rate of approximately 18.0%. (3) The formation and evolution of the southern section of the western Ordos Basin are closely linked to tectonic events along the margins of the North China Craton. It underwent several key stages, including rift extension during the Changchengian, uplift and denudation from the Late Ordovician to Early Carboniferous, multiple phases of intense thrusting and nappe formation in the Mesozoic, and modification during the Cenozoic. The large-scale intracontinental thrust structures primarily developed in the late Mesozoic, controlled mainly by the multi-plate convergence system in East Asia resulting from the subduction and closure of the Paleo-Pacific, Mongol-Okhotsk, and Bangong-Nujiang oceanic basins. The research findings provide important references for understanding tectonic deformation, evolutionary history, and petroleum exploration in the western margin of the Ordos Basin.
