Abstract: In accordance with the sediment volume distribution principle, the sequence boundary caused by sedimentary basic level of deposition cycle, and combining with drilling, logging and high resolution three seismic data, we do a high resolution sequence stratigraphy analysis on Permian sequence in Ordos Tabamiao block. The paper identified 3 mid term cycle, 19 short term cycles in upper Paleozoic carboniferous system exploration objective interval (Benxi formation to Shihezhi formation), established sequence formation framework, purchased space distribution characteristics of SSC4 cycle sand formation group and predicted the subtle trap in this sequence.
