Abstract
The loess tableland areas in southern Ordos Basin are unique in topography and morphology in China. The downward propagation of earthquake-induced energy in the weakly elastic thick loess is believed to be one of the global problems in processing seismic information collections. The highlights in the present paper are placed upon the key 3D seismic excitation techniques such as the selection of the excitation sites, decrease of the effects of dry and loose loess on the absorption and attenuation of seismic information, selection of reasonable excitation explosives and excitation parameters in order to increase the wavelet energy and expand the width of the wavelet frequency band widths, and suppression of the local lateral interference with the aid of combination effects. The progress in the key techniques of the 3 D seismic collection makes it possible to carry out the 3 D seismic exploration in the loess tableland area in southern Ordos Basin.关键词
