地震资料的复数道分析技术越来越受到人们的重视，它已广泛地应用于地震勘探的各个领域。在高分辨率地震勘探中，瞬时频率、瞬时相位剖面可以用来检测小幅度断层构造，在储层和岩性预测中，三瞬剖面可用来定性地识别岩相变化，在日益发展的浅层地震勘探中，复数道分析也已得到了广泛应用。如瞬时频率剖面可以帮助人们对金属矿的反射界面进行分析和解释。然而，目前复数道分析技术主要还是在地震资料专用处理机或工作站上实现的，硬件环境比较苛刻，这就限制了该技术的广泛应用。本文对复数道理论和算法进行了分析，并在微机上予以实现，理论和实际资料处理结果是令人满意的
The complex channel analysis technology of seismic data has drawn more and more attention. It has been widely used in various fields of seismic exploration. In high-resolution seismic exploration, instantaneous frequency and instantaneous phase profiles can be used to detect small-amplitude faults. In reservoir and lithology predictions, the three-moment profile can be used to qualitatively identify facies changes. In the increasingly shallow In seismic exploration, complex number analysis has also been widely used. Such as instantaneous frequency profile can help people reflect the metal surface reflection analysis and interpretation. However, the present complex channel analysis technology is still mainly implemented on seismic data processors or workstations, and the hardware environment is harsh, which limits the widespread application of the technology. In this paper, the theory and algorithm of complex channels are analyzed and implemented on a microcomputer. The theoretical and practical data processing results are satisfactory
