摘要
The basic principle of spectral inversion was elaborated and the realization workflow was given.By the application analysis of spectral inversion on single-trace model,wedge model and Mamousi model,we verified the effect of removing the impact of seismic wavelet from seismic record and obtaining reflection coefficient sequence,and revealed the compensation of frequency spectrum.Spectral inversion can identify the layer thinner than tuning thickness and improve the resolution of seismic exploration.In addition,spectral inversion can invert complex geologic model and is suitable to prospect the subtle reservoirs.
