Abstract: The Ankang area in southern Shaanxi Province holds favorable geological conditions for shale gas accumulation and shale gas resource potential. However, multistage tectonic processes have somewhat destroyed shale reservoirs. Pinpointing local favorable zones for shale gas accumulation has become a key issue for shale gas exploration in the Ankang area. Therefore, this study investigated the lower Cambrian Niutitang and Lujiaping formations in the Ankang area using the wide-field electromagnetic (WFEM) method. Through integrated information modeling and inversion imaging, this study determined the electrical structures of strata, fault structures, and the distributions of the bottom boundaries of the target layers in the study area. Moreover, combined with the organic geochemical characteristics of shales, this study identified the favorable and prospect zones for shale gas exploration. The results of this study provide significant guidance for further shale gas exploration in the Ankang area and a reference for other similar geophysical exploration of shale gas in China.
