摘要： 频谱成像将地震数据体从时间域转换到频率域, 利用分频处理技术大大提高了对薄储集层的分辨能力。从理论基础分析出发, 首先介绍了频谱成像的原理、最大分辨率, 然后结合国内某油田的实际情况, 阐述用频谱成像技术进行沉积相划分以及判断沉积环境水进水退的方法及实际效果。结果表明, 在勘探初期, 利用频谱成像特有的横向高分辨率特点, 可以很好地预测储集层的沉积环境变化及进行沉积相的划分。

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
