N2 - Locating in the mid west mainland of China, Ordos Basin is a cratonic petroliferous basin with stable subsidence, migrated depression and clearly twisted multicycle sedimentation. The interior of the basin has stable formations and relatively flat strata. However, it is difficult to use seismic means to detect oil-gas bearing strata, because of their irregular distribution, wide horizontal variation, and thinness of layers. Thus with generalized S transform (GST), and by analyzing the seismic response of typical alternative thin-beds, we constructed a high-resolution seismic sequence detecting method that determines the location of reflection interface according to the difference between multi-scale components. After analyzing seismic data of approximately 2000km of the basin, we developed the interpretation rules of sequence detection profile. The exploration result testified that the high-resolution seismic sequence profile obtained by GST is a favorable way to compartmentalize sedimentary microfacies, confirm sandstone strike and determine the distribution range of thin-bed oil-gas bearing sandstone.
