Embodiment Construction
[0046] specific implementation plan
[0047] The present invention collects pre-stack shots or CMP seismic records earlier, intercepts seismic records with conventional methods, generally selects the time window section with high signal-to-noise ratio of seismic records, and performs Fourier transform on seismic record segments with conventional methods, and converts seismic records from Transform the time domain to the frequency domain, and calculate the power spectrum, and then take the logarithm of each sampling point value of the power spectrum in the form of a lookup table to obtain the logarithmic power spectrum, transform the seismic record segment into a rematch spectrum, and convert the rematch spectrum truncated, followed by a surface-consistent decomposition.
[0048] Take the following specific steps:
[0049] 1) Collect pre-stack shots or CMP seismic records.
[0050] Seismic records can be set as x(t), t=1,...,N,
[0051] 1, ..., N are sampling points,
[005...
