| 摘 要： | 川中地区大安寨段地层为典型的碳酸盐岩，主要储层为大-亚段。模型正演结果表明地层厚度与地震振幅强度存在一定关系。当地震波经过油气层时，其高频成分能量衰减较不合油气层时严重；谱分解技术利用最大熵谱方法，将地震数据变换到频率域，其地震振幅强度表征了油气分布情况。振幅属性在J区块大安寨段的应用效果明显，既可以定性预测大-亚段厚度，也能预测油气分布情况。

| Abstract: | The Daanzhai Member in central Sichuan is a typical carbonate reservoir.A forward modelling shows that amplitude-frequency is related to stratigraphic thickness.Distribution of oil and gas may be characterized by amplitude-frequency.The application to the Daanzhai Member indicates that amplitude attribute may be used for predicting reservoir thickness and distribution of oil and gas. |
