A new method is proposed for drawing underground section, taking the place
of deconvolution method of reflected wave. Its physical basis is that all p
arameters of medium in moving situation are complex function of frequency.
The instantaneous spectrum of reflected wave in seismic prospecting obtaine
d by complex wavelet transform characterizes properties of its correspondin
g medium level. The new method of "3 basic colors" is used to abstract feat
ures from these spectrums and draw sectional figure. Using our wavelet soft
ware and practical seismic data obtained from oil field some figures are sh
own.
