Chang 6 oil-layer in Huaqing district of Changqing oilfield is a typical thick oil layer with ultra-low permeability. After 2 years' water flooding development, some of the production wells have been flooded with low oil recovery. Based on the geological model of Huaqing district, the ideal numerical models are established using the nonlinear flow numerical simulation software. Then the characteristics...
S transform has the characteristic of short Fourier transform and wavelet transform, but the basic wavelet in S transform is invariable and it isn't the same with seismic data absolutely. So a generalized S transform is discussed in the paper and used to predict thin bed. Simulation experiments and processing results of real data reveal that generalized S transform is feasible and effective to predict...
