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。
The Kuwait 3D project is a high count channels(over 200000 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.
