| 摘 要： | 根据双相介质理论 ,使用地震、地质资料反演出地震孔隙率和岩石地震应力。这两个参数从不同角度反映出地层的结构和骨架的弹性性质。由这两个参数组成的三角形地震岩性量板 ,显示出岩性分区规律 ,可区分不同岩石类型。利用该量板进行岩性预测和解释与岩性有关的疑难地质现象 ,取得了很好的效果 ,为岩性油气藏预测提供了新的手段。

| Abstract: | Seismic porosity and seismic stress of rocks can be inverted with seismic and geological data based on the theory of two phase medium. The two parameters can reflect porous structure and elastic property of rock frame. A triangular chart formed by the parameters is used to distinguish different lithology types. This technique has produced good results in predicting lithology and interpreting some difficult phenomena related with lithology,thus providing a new approach for predicating lithologic reservoirs. |
