摘要：A seismic processing method relating finely sampled data of earth formations,such as that obtained from borehole measurements, to substantially longer wavelengthseismic data, such as that obtained from surface seismic surveys or the like, whileimproving the ease of manipulation and processing speed of seismic processing. In apreferred embodiment, a fine layer model having n layers is defined, with the propertiesof each fine layer corresponding to the properties of each of n sampling points. Anequivalent model is constructed by defining m equivalent layers, where m is substantiallysmaller than n and the thickness of the thickest of the equivalent layers is substantiallysmaller than a predetermined dominant wavelength of a seismic signal. Equivalentformation properties are generated for each equivalent layer by combining the sampled

formation properties of the fine layers within the respective equivalent layer, preferablyin accordance with the equivalent medium theory. A synthetic seismogram is derived fromthe equivalent model and the seismic signal.
