Abstract:Using the Wide Field Electromagnetic Method, the authors ascertained the tectonic framework of the Changsan uplift area in southern North China basin. The relief and the burial depth of the basement, the main distribution of the strata in the work area were found out. The burial depth and the thickness of the low resistivity zone were determined so as to determine the favorable location of the shale layer. Interpretation results were verified by drilling recorder, and better geological achievement was gained. The results of the exploration provide very useful geological and geophysical information for the shale gas 'target' and 'dessert' area exploitation and show clearly the validity of the wide field electromagnetic method in detecting shale gas strata.
