The ancient grazing area on the southern margin of Junggar Basin has abundant oil and gas exploration potential;

nevertheless, due to the existence of blind areas in medium and deep layer seismic imaging, the structural characteristics of

this area remain unclear, which has restricted  the oil and gas exploration process. Using high-precision gravity and magnetic

and electrical CEMP integrated geophysical technique, the author studied the structural characteristics of the ancient grazing

area and obtained valuable new understanding. The results show that the structure of the ancient grazing area is the front

structure of Bogeda piedmont folded thrust zone. Controlled by step fault, the ancient grazing area is longitudinally

characterized by multi-layer structure, in which the shallow layer is tight type thrust overturned anticline, the medium layer is

ridgeshaped fault block controlled by step thrust, and the deep layer is thrust anticline covered by buried hill. Gravity

anomaly has revealed that the western pericline of the ancient grazing anticline is probably a complete anticline structure. The

medium and deep structure of the ancient grazing area and the western pericline seem to be favorable targets for oil and gas

exploration.
