摘要
地震反演是研究储集层分布的有效方法,但如果地震资料分辨率低就很难满足要求。地震反演资料分辨率的高低很大程度上取决于地震子波。提出的用高阶统计量法求取的地震子波,比用常规方法提取的子波更接近真实的地震子波。经用两者反演对比,前者反演的地震资料连续性和分辨率明显提高。这表明,该方法对提高反演资料的分辨率有很好的应用前景。
Seismic inversion is an effective method for study of reservoir distribution, but it can hardly satisfy the demand when available seismic data are in low resolution. Whether the resolution of inversion data is high or low depends on the seismic wavelet to a large extent. This paper proposes the higher order statistics method by which the seismic wavelet taken is more similar to the real seismic wavelet taken by the conventional method. By comparison between the two methods, the seismic data inversed with higher order statistics method are obviously improved in seismic data continuity and resolution, showing that it has a good application potential for improving seismic data resolution.
