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.%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.
