摘要

微地震技术是一项利用微地震识别和描述油气地质构造的新方法、新技术,是一套信号采集、处理和分析技术,可以对火山岩、碳酸岩及油气藏有关的自然出现的低频地震波谱信号进行识别并作图。火山岩、碳酸岩及油气藏微地震分析可以解决其速度差异成像和地层成像问题,把地球内部存在的地震背景噪音作为火山岩、碳酸盐岩及油气藏微地震分析显示信号的震源,利用地震背景噪音谱,因地质构造介质不同及不同岩性差异而引起的透射损失,从而成为分析低频地震信号识别和描述油气地质构造的手段和方法。
Microseism technology is a new method and technology using microseism to identify and describe hydrocarbon geology structure.It is mainly a set of signal pickup and processing and analyzing technology,can identify low frequency seismic spectrum signal naturally occurred in igneous rock and carbonate rock and related hydrocarbon reservoir and make diagram.Microseism analysis can tackle the problems such as velocity difference image and stratum image.It regards the seismic background noise existed in the interior of earth as seismic source of microseism analytical signal of igneous rock and carbonate rock and hydrocarbon reservoir,uses seismic background noise spectrum,because various geological structure media and lithology can lead to transmission loss,it becomes a means and method to analyze and identify low frequency seismic signal and describe hydrocarbon geology structure.
