CWP/SU地震数据处理软件研究与应用
|
摘要
CWP/SU是美国科罗拉多矿业学院波场处理中心开发的一款免费的地球物理开源软件。其主要研究地震建模和成像,地震反演理论,以及复杂地质体地震数据处理算法,既可以作为地震数据处理环境,也可以作为波场处理的相关软件的研究与开发环境。其广泛应用于地震勘探开发领域,是一个很好的学习工具。本文主要是以SU地震处理软件为平台,进行了三个方面的研究与应用:基于SU的地震正演模拟;LIFT去噪方法在SU中的实现;基于SU的地震延时校正程序编写。
CWP/SU is a free and open-source geophysical software established by the Center for Wave Phenomena at the Colorado School of Mines.The main program is focused on seismic modeling,imaging,and inversion methods,as well as seismic processing algorithms for complex structural.It can be used for both seismic data processing and the programme research and development on wave field.It is a very useful learning resource,widely used in exploration of geophysics.Based on the platform of SU,this paper has done some research including three aspects:forward modeling,implementation of multiples attenuation using LIFT technique and programme development of seismic data delay time correction.
