The author takes the high resolution sequence stratigraphy and the fine river sedimentology as the instruction, according to the principle, “the cycle contrast, the step control, the differential phase belt the differential treatment” , builds the high resolution sequence stratum rack of the single time rivers short-term sequence, distinguishes two kind of subfacies and 11 kinds of microfacies, delineates 28 sedimentation units sandbody in Sa Ⅱ,Sa Ⅲ group, has established 4 types of channel sandbody depositional mode. The authors takes the further study to the reservoir heterogeneity, establishs the reservoir plane and the vertical reservoir non-isotropic pattern, the sublevel for compound river course-single sandbody-side sedimentary body.
