Abstract：Under demands of precise exploration, method for analyzing distributions of sand in short time domain is a hot point in recent years. Toutunhe formation in Fudong slope area, east of Junggar basin was taken as a study example. The high-resolution sequence stratigraphic framework was built based on outcrops, cores, seismic and logging data. Isochronic rock combination with synchronous sedimentary revolution sequence was divided by chronostratigraphic units of relative times. Multi-attributes were selected to reveal seismic characters of rock combination in relative time through dimension reduction and fusion. The distribution of sand body could be predicted in short time domain through integration of the above methods. The results show that sand body in SSC1—SSC10 of Toutunhe formation has foreset from Northeast to Southwest. The sand body are the main exploration targets for its thickness and good succession. Thickness of sandstone predicted was match well with the drilling wells, this brought a new method for precise sand body prediction in similar regions.
