摘    要:地震相干体技术可以有效地压制连续性,突出不连续性,比地震切片的地质解释更直观,能更细致地进行断层解释。基于Manhattan 距离的相干体技术,与传统的C1 相干算法进行比较,该技术不仅在断层识别能力方面要强于C1 相干算法,而且当利用两种算法获取断层信息的效果相当时,该技术的相关时窗长度要比C1 相干算法所用的相关时窗长度小,这恰能提高程序的运行速度,提高了地震相干体技术的运行效率。此外,该相干体技术也能近似计算出每道在纵横测线方向上的视时间倾角。

关 键 词:相干体技术  C1  相干算法  Manhattan  距离  断层识别

Abstract:Seismic coherence technique can effectively suppress the continuity and highlight the discontinuity, which is more intuitive than those of the geological interpretation of geological slices and has more detailed interpretation on the fault. Compared the coherence technique based on the Manhattan distance with the C1 coherence algorithm, this technique is not only stronger than C1 coherence algorithm in fault identification capabilities,but also has the smaller time window than the C1 coherence algorithm when the two algorithms have equivalent fault information, which can improve the speed of program and the operating efficiency of seismic coherence techniques. The coherence technique based on the Manhattan distance can also compute the visual time angle of every path in horizontal- vertical lines approximately as the C1 coherence algorithm works.
Keywords:coherence technique  C1 coherence algorithm  Manhattan distance  fault identification
