The sedimentary microfacies of lake delta are divided and described in detail in the 2nd Member of Shahejie Formation of Tong 61 block in Dongying depression especially by using seismic and logging data. Microfacies maps were drawn up systematically, and a model of lake delta is given. The controlling of sedimentary factes to petroleum accumulation are discussed. Subaqueous distributive channels, mouth bars, distal mouth bars and shallow lake bar sand-bodies are considered to be favorable reservoirs.
