【摘要】 在对地震资料进行预处理并综合应用相干体技术、方差体技术等多种地震属性技术检测地震反射不连续性的基础上,应用蚂蚁追踪技术对黄珏南地区三维地震资料进行断裂系统的自动解释,基于断裂自动解释结果提取黄珏南地区的三维断片系统,并将自动解释成果与人工解释方案进行对比。结果表明:在应用方差体技术对地震反射不连续性进行检测的基础上进行蚂蚁追踪得到的属性体断裂痕迹显示更加清晰直观,可以有效地指导断裂的平面及剖面解释;黄珏南地区主要发育一组近东西走向的断裂,呈阶梯状展布,断面北倾,一般倾角较大;蚂蚁追踪解释的主要断裂发育特征基本符合构造成因机制预测的断裂发育规律,这进一步验证了方法的实用性和有效性。更多还原

【Abstract】 On the basis of the pre-processing of seismic data and the integrated application of multiple seismic attribute technology such as the coherence and variance technique to detect reflection discontinuities in the seismic data,the ant tracking technology was applied in the automatic fault interpretation of the seismic data in south Huang-jue area.Based on the results of automatic interpretation,the three-dimensional fault patches were extracted and the artificial job was also compared with the automatic results.The results show that the fault traces of the attribute volume obtained by the ant tracking technology based on the detection of variance technique over the reflection discontinuities are much more distinct and can be used to effectively guide the fault interpretation both in the plane and the section.It is also concluded that a group of graded faults are developed with nearly EW strikes,N tendency and generally large dip.The main fracture characteristics interpreted by the ant tracking technology agree well with the law of the fault development predicted by structural genesis mechanism,which also proves the technology is effective and practical.更多还原
