用于断层解释的地震属性有相干类、谱分解类、曲率体属性等多种。综合利用这些地震属性的时间切片与地震剖面,可提高小断层的解释精度。近年涌现的图形处理技术将表征断层的地震属性进行图形处理,增强了断层体属性纵向上的连续性,同时压制与地震反射同相轴相关的横向信息,并将断层属性从围岩中提取出来,嵌入到地震数据体中,能够更加准确地识别断点位置,进一步提高小断层的解释精度。
Seismic attributes used for fault interpretation include coherence class, spectral decomposition class and curvature body property. The comprehensive utilization of time slices and seismic profiles of these seismic attributes can improve the interpretation accuracy of small faults. In recent years, the graphics processing techniques have been used to graphically characterize the seismic attributes of faults, enhance the vertical continuity of fault attributes, suppress the lateral information related to the seismic reflection events and extract the fault attributes from the surrounding rock. Embedded into the seismic data body, it can more accurately identify the location of breakpoints and further improve the interpretation accuracy of small faults.
