【摘要】 通过对叠后数据体资料进行修饰性处理,获得高信噪比的地震资料,采用时窗扫描法确定合适的控制时窗,提出能准确反映含油气储层变化特征的属性资料。采用该方法在托浦台石炭系砂泥岩储层预测中,对提取的属性资料进行分析筛选,发现在该工区振幅和频率等属性能较好的反映该区含油气储层的变化特征,取得了较好的效果。更多还原

【Abstract】 The post-stack data is processed in the paper and the seismic data with a high signal-to-noise ratio is obtained.In the article,appropriate controlling time window is determined by window scanning method and the attribute data containing oil-gas reservoir changing characteristics are accurately proposed.By this method the extracted data are processed in the sand-mud rock reservoir prediction in carboniferous and it is discovered that the features such as amplitude and frequency in this area can well show the changing characteristics of the oil-gas reservoir,therefore the distribution range of the reservoir can be predicted.更多还原
