【摘要】 研究了相干数据体的C3算法以及方差数据体算法,编制开发了利用相干和方差数据体技术进行地震资料处理的数据处理系统,利用相干和方差数据体的时间切片和顺层切片来分析相邻道地震信号的相似性,进而探测小断层和分析地质构造。通过对实际资料的分析解释可以看出,相干和方差数据体技术对断层解释是非常有效的,可以提高解释精度,缩短勘探周期。更多还原

【Abstract】 The coherency/variance cube technique has been developed in recent years as a new technique of seismic data interpretation.In this paper,C3 coherency and variance cube algorithms are emphatically discussed.The authors have designed a software for processing seismic data in the coherency/variance cube technique.Using time slice and leveled layer slice,we can explore small faults and analyze geological structures through investigating the similarity of seismic signals between adjacent traces on the seismic cube.An analysis and interpretation of practical data show that the coherency/variance cube technique is very effective in fault interpretation in that it can improve the interpretation precision and shorten the exploration period.更多还原
