多属性聚类分析技术在八面河西区中的应用

储层参数的变化引起地震属性的变化,但是储层参数与地震属性的变化并没有一一对应的关系,为解决此问题采用地震多属性聚类分析技术。通过属性优选,将弧长、上半周持续时间、带宽、最小振幅、瞬时频率五种对沙四段1砂组储层敏感且相互独立的地震属性参与聚类分析,取得了较好的应用效果。

The change of reservoir parameters leads to the change of seismic attributes, but there is no one-to-one corresponding relationship between reservoir parameters and seismic attributes. Seismic multi-attribute clustering analysis is used to solve this problem. Through attribute optimization, five kinds of seismic attributes, such as arc length, duration of the first half cycle, bandwidth, minimum amplitude and instantaneous frequency, which are sensitive and independent to the reservoir of ES4 member 1 sand group, are involved in cluster analysis, and good application results are obtained.
