Abstract: Dongying Depression is a typical continental rift basin in eastern China.Against the background of the special structure of the northern steep slope,many kinds of sandy-conglomeratic fans have been formed in the strata,which become the major exploration target now.On the basis of integrated studies of geologic and seismic faces about six kinds of those fans,the paper presents the areal distribution in the same formation,evolution in horizontal or vertical direction and combined mode of sections.On account of the fans complexity,author summarized the exploration technique and methods of identifying,tracing,describing and predicting the horizons representing fans, which have lead to exploration effect in this area and provided successful experience for the exploration of this kind of fan.

Key words: Dongying Depression, steep slope, fan, reservoir, exploration technique
