历史上,地质事故主要是用高分辨的2-D单道地震(即3.5kHz的微电火花记录)、侧向扫描声纳测量、从选择井孔中和现场测量的岩土工程数据和保留的岩心进行识别。然而,有效地使用常规3-D地震资料的相干和其他地震属性能够在进行高分辨的危险区测量之前及早地发现和划分出地面及地下的地质钻井“危险区”的范围。 Historically, geological incidents have been dominated by high-resolution 2-D single-channel earthquakes (ie, 3.5kHz micro-spark recording), lateral scan sonar measurements, geotechnical data measured from selected boreholes and on-site and retained The core of the identification. However, the effective use of coherence and other seismic attributes of conventional 3-D seismic data allows for the early identification and delineation of surface and subsurface geological drilling “zones of danger” prior to high-resolution hazard zone measurements.
