一种PS波与PP波反射时间匹配方法
A Method for PS to PP Reflection Time Mapping
摘要
Abstract
PS to PP time mapping is one of key factors affecting seismic reservoir predictions in multi-component seismic interpretations. Based on prior work, a new method is presented for the ratio of com-pressional velocity and shear velocity scanning and PS to PP reflection time mapping with using converted-wave prestack data. Model data results show that converted-wave velocity , the ratio of compressional velocity and shear velocity can be obtained directly from converted-wave seismic gathers, and P wave and PS wave reflection time can be automatically matched by means of the method presented. It works well with model data, suits for multicomponent seismic data processing in an area with horizontal formation.关键词
