Abstract: Spectral imaging can be used to convert seismic data from time domain to frequency domain, and the resolution of thin reservoirs can be greatly improved using its separate frequency processing technique. This paper presents the principle and the maximum resolution of the spectral imaging followed by taking a case study as an example to discuss the application of this technique to sedimentary facies classification and the practical significance of it in progradation and retrogradation identification of sedimentary environment. The study shows that this technique can be used to well predict the changes of sedimentary environment of reservoirs and classify the sedimentary facies in the early of exploration by means of its feature of lateral high resolution.

Key words: spectral imaging, separate frequency processing, resolution capability, sedimentary facies
