Over 4000 meters of lacustrine face coal and oil-bearing clastic rock are deposited above the lower Permian base rock in Hurenbuqi sag, suggesting a good prospect of oil and gas geological conditions and resources. In this paper, the authors discuss the anomaly pattern of soil hydrocarbon geochemical exploration based on the magnetotelluric sounding interpretation of fracture structure and stratigraphic distribution as well as anomaly characteristics of southern sag. The formation mechanism of the surface geochemical anomalies are investigated, and the geochemical anomaly models are analyzed. The results obtained by the authors will play an extremely important role in oil and gas prospect evaluation.
