文章摘要
change in two-dimensional space as well as lateral extension contrast, we developed a method of wavelet
depth-frequency analysis. The single signal and composite signal of different Milankovitch cycles are
obtained by numerical simulation. The simulated composite signal can be separated into single signals of
a single frequency cycle. We also develop a well-seismic calibration insertion technology which helps to
realize the calibration from the spectrum characteristics of a single well to the seismic profile. And then
we determine the change and distribution characteristics of spectrum cycles in the two-dimensional space.
It points out the direction in determining the variations of the regional sedimentary sequence cycles,
underground strata structure and the contact relationship.
