| Abstract: | Taking the seismic exploration of the loess tableland of huge thickness in the southwestern Erdos Basin as an example,the factors of influencing the signal-noise ratio of the loess tableland seismic data are analyzed in order to predict the reservoir characteristics of Mesozoic and Paleozoic and describe their paleogeomorphology,and a series of denoising methods are proposed,including united static correction,surface consistency remaining fine correction,high-precision velocity analysis,multi-area or multi-... |
