基于Qt的VSP波场分离系统的设计与实现

摘要

VSP技术是近几年发展比较迅速的一种重要地震观测方法,如何有效地分离上、下行波,是应用VSP资料所要解决的首要问题.介绍了几种常用的VSP波场分离方法原理及其实现步骤,利用跨平台的C++图形用户界面库Qt,开发了VSP波场分离系统.系统操作界面友好、功能强大,已在实际资料处理中得到很好的应用.%The technology of VSP is a very important earthquake observation method and is developing very fast in recent years. How to separate the wave-up and wave-down curve efficiently is the critical problem for applying the VSP data. This paper introduces several common methods to separate wave field of VSP, and a system is developed, which is by using the cross-platform Qt graphical user interface software library. The system is very powerful and the operation Interface is friendly . It has been well applied in the actual data processing.
