Abstract: Guantao formation is riveral depositional system in Gudong area,riveralsands lithologic trap development,it is a typical sandstone reservoir lithology concealed type, therefore, strengthen the channel sandbody identification description and evaluation studies can be achieved riveralsands exploration breakthrough in Gudong area. In this paper, to the geological characteristics of Guantao in Gudong area,base on high-precision three-dimensional seismic data, the formation of a "horizontal sections, logging constrained inversion, seismic attribute analysis, three-dimensional visualization and evaluation of hydrocarbon detection" and other exploration techniques, riveralsands identification techniques described in a comprehensive study has an important role to riveralsands exploration of Guantao formation in Gudong area.
