基于波阻抗反演的本征值相干属性的应用,实现对裂缝、断层和褶皱等地质构造的有效识别。介绍了相干属性的基本理论,分析了未经过波阻抗的地震数据体的相干属性在处理实际资料中的不足,提出了一种基于波阻抗反演的地震数据体来表现本征值相干属性的方法:对原始数据体进行波阻抗反演的处理,将处理后的地震数据体进行第3代相干属性的求取,然后对经过2种方法得出的地震属性的成图效果进行比较,分析异同,得出结论表明基于波阻抗反演的相干属性在高分辨率构造精细识别和裂缝的判别、构造体的几何特征描述上有着良好的应用效果。
Based on the application of wave impedance inversion of eigenvalue coherence properties, effective identification of geological structures such as cracks, faults and folds is realized. This paper introduces the basic theory of coherent property, analyzes the shortage of coherence property of seismic data body without wave impedance in processing actual data, and proposes a seismic data body based on wave impedance inversion to express coherent property of eigenvalue Methods: The inversion of wave impedance was performed on the original data. The seismic data body was processed for the third generation of coherent properties. Then the mapping results of the seismic attributes obtained by the two methods were compared and analyzed. The similarities and differences show that the coherence attributes based on wave impedance inversion have a good application effect in fine structure recognition and fracture identification of high resolution and geometric feature description of structures.
