摘要
本文以Curvelet变换为基础,提出了一种预测断层和裂缝发育带的方法。基于Curvelet变换的多尺度性、多方向性和强局部化功能,在曲波域中给出了不同的重构系数,得到突出不同频带和不同方位的地震数据体,然后结合相干体边缘检测技术,对断裂和裂缝发育带及其走向进行预测。通过模型和实际地震资料应用说明了方法的有效性。
Based on Curvelet transform,a new method is proposed in this paper to predict faults and fracture zones.Appling the multi-scale,multi-direction and strong localization characteristics of Curvelet transform,the method gives the different construction coefficients in the Curvelet domain,obtains seismic data with different frequency bands and different directions,and then combines with coherence edge direction to predict fractures and fracture zone strikes.Applications of the method on model data and real seismic data show its effectiveness.
