摘要
This paper discusses the migration result of different frequency wavefields in both crosscorrelation and deconvolution imaging conditions by the construction of attenuation coefficients which are based on the receiver-source energy ratio.The distribution characteristics of the receiver-source energy ratio can be used to overcome the instability in the deconcolution imaging condition if the nominator approaches to zero,and smooth both the receiver and the source wavefields.If the receiver-source energy ratio exceeds a reasonable range,it will lead to illumination irregularity in the migration results.The ideas in this paper can be used to improve the migration processing,and to guide the illumination technology of making the amplitude correction in the migration results.
