摘要
曲率属性对于裂缝检测、断层解释储层检测有很好的实用价值。曲率与层面的二阶导数密切相关,常规方法是在计算曲率前对层面进行适当的二维滤波预处理,但其对一些信噪比较差的地震资料的处理效果不佳。为解决这类问题,采用了先计算曲率后进行二维滤波的方法,使研究对象数据与周围数据差异很小的地震资料得到了很好的处理效果,对曲率属性分析的应用,断层解释及开展储层检测有一定的实际应用价值。
Curvature properties has good practical value for crack detection, fault interpretation and reservoir check. Curvature is closely related to second derivative, for conventional method before calculation of curvature we always do 2D filtering to the bedding plane first. But conventional method is not good for low SNR data. To solve this problem, we test to do curvature calculation before 2D filtering. It gets very good effect in the seismic data that object data points has low difference with ambient data points. It has certain actual application value for the analysis of curvature attribute application and fault interpretation.
