Abstract: Buried hill,deep geological body and glutenite are the relatively difficult exploration targets in Dongying Sag.Aiming at this problem,line SL616 with a total length of about 100 km was utilized to discuss gravity-magnetic-electric-seismic integrated interpretation method;the line is located in the east of Jiyang Depression,crossing three secondary structure units,including Guangrao Salient,Dongying Sag and Chenjiazhuang Salient.The 3-D Euler deconvolution for aeromagnetic data,rapid relaxation inversion for electric data,constrained forward modeling and inversion methods for gravity data were introduced.Some subtle geologic targets,such as buried hill and glutenite,which have shielding effect in seismic exploration,also have obvious anomaly on gravity-magnetic-electric data.Through integrated analysis of gravity,magnetic,electric and seismic data,the inner buried hill,glutenite,boundary fault and deep formations were re-identified,and new geologic bodies were found.The result shows that Chenjiazhuang Salient is not the unique Archaean strata,fault,low-resistivity and low-density bodies exist inside the salient.From the seismic data,the deepest Paleozoic strata in Dongying Sag should be shifted northward.
