【摘要】In an effort to reduce the shale gas exploration risks and costs,we

applied

of

the its

wide-field strong

electromagnetic

method

(WFEM),because anti-interference capability,high

resolution,ability to conduct exploration at large depths,and high efficiency,to the Bayan Syncline in the South Huayuan block,Hunan Province.We collected rock samples and analyzed their resistivity and induced polarization (IP) and built A series of two-dimensional models for geological conditions to investigate the applicability of WFEM to different geological structures.We also analyzed the correlation between TOC of shale and the resistivity and IP ratio to determine the threshold for identifying target formations.We used WFEM to identify the underground structures and determine the distribution,depth,and thickness of the target strata.Resistivity,IP,and total organic carbon were used to evaluate the shale gas prospects and select favorable areas (sweet spots) for exploration and development.Subsequently,drilling in these areas proved the applicability of WFEM in shale gas exploration. 【总页数】8页(441-448)
