Abstract: On the basis of the characteristics of architectural elements, sandstone grain size analysis, and fluvial styles of the Upper Members of Guantao Formation in Gudao oilfield, and according to stream features of 16 kinds proposed by Miall, we believe that it belongs to fine grain meandering stream. Among architectural elements, floodplain fines (FF), crevasse splay (CS) and lateral accretion macroform (LA) developed extensively, and levee (LV) and crevasse channel (CR) also developed. The channel sinuosity (P) is more than 2.2. The channel is 100~300 meters wide. The channel meander wavelength is 1 000~1 770 meters. The stream may be adjacent to an estuary, and development of sandstone bodies may be subject to fluctuation of sea level.
