相干体技术是利用相邻道地震信号的相似性来检测地震同相轴的不连续性,可以用来识别断层、特殊岩性体、河道等地质现象。在概述了第一代相干体两道互相关算法(C1)、第二代相干体多道相似系数算法(C2)、第三代相干体特征值算法(C3)及其特点的基础上,改进了基于本征值结构的C3相干体算法。结果表明,改进算法具有更好的信噪比和分辨率,计算速度进一步提高。在独立自主研制的GeoMountain解释工程师软件系统平台上开发出相干体分析软件,给出了相干体算法应用实例。
Coherent technology is the use of the similarity of adjacent seismic signals to detect the seismic events of the discontinuity, which can be used to identify faults, special lithology, river and other geological phenomena. On the basis of an overview of the first generation coherent correlation algorithm (C1), the second generation correlation coefficient multipath similarity coefficient (C2), the third generation coherent eigenvalue algorithm (C3) and its characteristics, the improvement A C3 Coherence Algorithm Based on Eigenvalue Structure. The results show that the improved algorithm has better SNR and resolution, and the computational speed is further improved. Developed the coherent body analysis software on the independently developed GeoMountain Interpretation Engineer software system platform, and gives the application example of the coherent body algorithm.
