摘要
本文基于高精度三维地震数据,通过模型正演,综合应用相干体、曲率体、构造导向滤波等技术(和时间切片、大比例尺工业制图等手段),较好地识别出约1300m深度处3~5m断距的微断层和3~5m的微幅度构造,取得了较好的地质效果。
This paper describes micro-fault interpretation by seismic attributes.Based on the high-resolution 3D seismic data,micro-faults with throw of 3~5m and structures with small relief can be detached effectively at the depth around 1300m using the forward model and different techniques such as coherence volume,curvature volume,structure-direction filter,time slice,large scale mapping,and so on.The results achieved have great geological significances.
