| 摘 要： | 基于常规复数道分析方法计算地震信号瞬时特征参数,用于常规地震剖面解释中,其精度完全可以满足要求。但对高分辨率地震勘探,特别是对薄层的研究,其精度就不够了。在充分研究常规复数道分析算法及应用效果的基础上,提出了能够用于高分辨率资料解释的新复数道分析的方法。模型算例和实际资料处理结果表明,该方法可以有效地提高地震资料的分辨率。

| Abstract: | Used to interpret conventional seismic Profiles,the instantaneous characteristic parameters of a seismic signal based on conventional complex trace analysis method,its precision is fully adequate.But for the high-resolution seismic exploration,especially for the study of thin bed,its precision is inadequate.This paper,based on the full research on the conventional complex trace analysis algorithm and its application effect,a new high-resolution complex trace analysis method is proposed,it can be used to interpret the high-resolution seismic data,and the numerical simulation and actual data processing results show that the method can effectively improve the resolution of seismic data. |
