| 摘 要： | 科威特某项目采用G3iHD采集系统及与SL11数字检波器配套的超大道级采集技术方法进行地震数据采集，并在室内进行组合处理来提高数据的信噪比和分辨率。但技术人员处理资料时发现，资料存在高频成分衰减严重的问题。为此设计多种对比实验，并结合地质综合研究等方法分析科威特地区高频信号衰减原因。结果显示，地质因素是科威特地区高频信号衰减严重的主要原因。

| Abstract: | The Kuwait 3D project is a high count channels (over 200 000 channels in a live super-patch) project which firstly applies INOVA’s G3iHD acquisition system and the SL11 digital sensor. The project uses a single-point receiving, sub-line combined geometry, and the data is a digital group forming indoors to improve the signal-to-noise ratio and resolution. However, after technical staff processed the data, we find that the high-frequency components of the data are seriously attenuated. This paper investigates the reasons for the attenuation of high-frequency signals in Kuwait through experimental analysis and geological research. Geological structure is the main reason for the high-frequency attenuation. |
