Abstract：The gentle slope of sag near the source sag is generally the prospective zone of development of lithologic reservoir. The various reservoirs developed on the gentle slope are mostly closely relative to valley on the gently-dipping slope. The superior analysis of palaeovalley can diminish the multiple solutions from predicting sedimentary system by seismic facies and reduce reservoir-predicting risk. Combination with the knowledge of sequence stratigraphy, we further analyzed the sedimentary feature of valley on the gentle slope, summed up development feature of prospective reservoir in different sedimentary system on the valley of gentle slope of sag and different hydrocarbon migration effect produced in different sedimentary environment of valley, which has guide meaning for the exploration of stratigraphic and lithologic reservoirs affected by valley development on gentle slope of sag.
