地震多矢量属性相干数据体计算及应用

THE CALCULATION AND APPLICATION OF COHERENCE DATA BODY OF SEISMIC MULTI-VECTOR ATTRIBUTES

在对相干分析算法研究的基础上 ,研究了一种新的相干分析算法—基于特征值结构的地震多矢量属性相干算法。该算法克服了单一属性相干算法的信息量不全的缺陷。既充分利用多属性的多方位信息 ,又要使其相互之间不发生矛盾 ,最大限度提高地质体边界的分辨率。经实际资料分析验证 ,结果非常理想。

On the basis of coherence algorithms, a new method, i.e., coherence algorithms of eigenstructure-based seismic multi-vector attributes, is studied in this paper. With this method, we can overcome the defect of insufficient information obtained from the singular attribute technique. The multi-vector attributes can be fully used without any contradiction between them. In addition, the geological boundary can be well distinguished. An analysis of the practical data shows that the result is very satisfactory.
