地震三维矢量反射波场

Three dimensional vector seismic reflection field

三分量反射地震的本质是三维矢量反射波场.与应力有关的岩体内部细结构是导致三维矢量反射波场的普遍原因.本文讨论三维矢量反射波场所涉及的理论方法、数据处理、观测解释及介质信息提取等问题,总体格架是通过我国自主创新发展从原构造成像提升到构造-岩体内部细结构的复合成像.

The essence of three component seismic reflection is three dimensional vector reflection field. The stress related fine internal structure of rockmass may be the common cause of such vector reflection. In this paper, the theory and method, data processing,observation explanation as well as information extracting associated with three dimensional vector reflection field are discussed. The composite imaging both for tectonic and fine structure of rockmass is worked out form previonis imaging by innovative develop ment on one＇s hand in our country. As the whole framework, It could promote the transition from previous tectonic imaging to further composite imaging both for tectonic and fine internal structure of rockmass through innovative development on one＇s own hand in our country.
