| 摘 要： | 在地震资料精细解释的基础上,以地震属性优化为前提,以K-L变换为手段,对原始地震属性进行了优化处理。经变换后地震属性特征维数下降十分明显,选取的地震属性之间的相关性得到明显降低,突出了其间的差异性,降低了多解性。在利用优化后的属性进行储层预测时,储层参数更加精确。

| Abstract: | on the basis of fine interpretation of seismic data and in combination with seismic attribute optimization,the original seismic attribute was optimized by means of K-L transform.Its transformed characteristic dimensions and correlation between selected attributes were obviously reduced,the differences between them were indicated,while multi-interpretations were reduced.Reservoirs are predicted,more accurate reservoir parameters are obtained by using the optimized attribute. |
