Abstract: The Ordos basin, one of the large hydrocarbon bearing basins, is located in the west part of North China. There are many big basement faults making up a complex pattern with two uplifts lying on the top of the basement. The complex and heterogeneous basement structure controls obviously the overlying sedimentary lithology and its formation, and influence indirectly the generation, migration and accumulation of hydrocarbon. The south slope of the northern Yimeng Uplift and the slope region around the central uplift are favorable for seeking Paleozoic natural gas. Several large northeastern ductile shearing belts may influence the hydrocarbon distribution greatly and much attention should be devoted to the oil and gas exploration.
