| 摘 要： | 由于地球物理方法本身受分辨率和保真度的限制,其在断层和裂缝识别上的应用也就有精度和尺度上的差异。为此,可采用不同的方法技术来识别不同尺度的断层和裂缝,即在断层识别上,利用地震剖面和水平切片解释大断层,采用相干分析方法识别小断层;在裂缝识别上,主要采用多方位AVO方法识别大尺度裂缝的发育特征,采用成像测井来识别微小裂缝的特征情况。实际应用表明,上述方法在相应尺度断层和裂缝上的识别效果较好。

| Abstract: | Geophysical technique itself exists restriction of resolution and fidelity, so it has different precision levels and scales in the application of fault and fracture identification.Therefore, we use different techniques to identify the fault and fracture at different scales: for the identification of faults, the large faults are interpreted by the seismic cross section and seiscrop section, while coherence analysis and other new technique is used for the small faults; on the identification of fracture, multi... |
