利用背景噪声进行地震成像简述
|
摘要
背景噪声是一种连续稳定的自然源,其中包含丰富的地下介质信息。利用背景噪声成像技术可以获得对研究区域的地下速度结构认识,为深部构造研究提供了新方法。主要论述其发展历史、原理及其在地震领域方面的研究现状,探讨该方法在未来需要解决的问题以及发展方向。
The background noise is continuous and stable naturally, which contains rich information about subsurface media. The background noise imaging technique can be used to obtain the subsurface velocity structure of the studied area, which brings a new method to the deep structure study. This paper mainly discusses its development history, principles and the study status in the seismic field. Finally, the problems needed to be solved and the development directions of the method are discussed.
