In this paper the magnetotelluric sounding and 2D seismic exploration methods were applied to study the deep stratigraphic structure and concealed faults of in western region of Taikang Uplift, Southern North China Basin. Seven MT profiles had been deployed which included 63 MT sites and 16.24 kilometres of two 2D seismic had been laid for in the study area. By using different advanced data processing and inversion algorithm, the reliable underground geoelectric models and multiplicity of reflection zone were obtained. The results show that the boundary of the base of the Neogene thermal reservoir and the top of the Ordovician thermal reservoir were finely calibrated. Five faults can be accurately interpreted with geophysical exploration. Based on the seven MT profiles and two the seismic profile interpretation as well as geological survey, geophysical exploration, the engineering geological drilling exploration, the boundary isograms of the base of the Neogene thermal reservoir and the top of the Ordovician thermal reservoir were delineated.
