【摘要】 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。更多还原

【Abstract】 In recent years,quite a few new seismic interpretation techniques are used for fault identification,such as coherence,spectrum decomposition,curvature and etc.Combining seismic attributes with seismic sections,minor fault identification can be greatly improved.The newly developed image processing and analysis techniques are used for characteristics of fault seismic attributes.So the longitudinal continuity of fault seismic attributes is enhanced,and the background clutter is also minimized.Then fault properties are detected from the surrounding rocks and embedded with the seismic data to identify accurately the breakpoint location of minor faults.更多还原
