Abstract

The procedure of 3D seismic diffraction imaging for the depth structure followed by calculation of the diffraction attributes is considered. The algorithm is based on asymmetric summation of seismic data and makes it possible to identify three characteristics of the medium: the structural diffraction attribute, the point diffraction attribute, and the structural diffraction azimuth. These attributes allow one to distinguish between the fracture and cavernous zones and to determine the orientation of fractures. The practical evaluation of the approach is presented on real seismic data.

摘要

考虑了对深度结构进行 3D 地震衍射成像,然后计算衍射属性的过程。该算法基于地震数据的非对称求和,可以识别介质的三个特征:结构衍射属性、点衍射属性和结构衍射方位。这些属性允许人们区分裂缝和海绵状区域并确定裂缝的方向。该方法的实际评估是在真实地震数据上提出的。
