高分辨率反射地震正逐步应用于解决地质勘探及工程问题。然而,在结晶岩环境中应用反射地震技术时仍存在很多问题。当结晶岩中存在裂隙时,采集的反射地震数据的信噪比常常很低,反射同相轴也不够连续。因此,研究结晶岩裂隙带成像时的数据处理与校正方法是很重要的。我们对以前采集的两个数据集重新进行了处理和分析,研究重点是60～100米深度上的浅层反射同相轴。该数据集分辨率很低,信噪比较高,分别由两个不同的承包商在加拿大Pinawa和瑞士的“ASPO”岛采集而得。处理策略之一是增强隐含在大幅
High-resolution seismic reflection is gradually applied to solve geological exploration and engineering problems. However, there are still many problems when using reflected seismic techniques in the crystalline rock environment. When fissures are present in the crystalline rocks, the signal-to-noise ratio of the acquired reflected seismic data is often low and the reflection events are not continuous enough. Therefore, it is very important to study the data processing and correction method in the imaging of crystalline rock fracture zone. We have reprocessed and analyzed two previously collected datasets, focusing on shallow reflection events at depths of 60 to 100 meters. This dataset has very low resolution and high signal-to-noise ratio and was collected by two different contractors on the “ASPO” island in Pinawa, Canada and Switzerland. One of the strategies to deal with is that implicitness is substantial
