| 摘 要： | 莺歌海盆地主要舍气储集层是粉砂岩与极细砂岩，在无测井资料的情况下，很难用地震波一般属性参数直接区分砂岩的含水与舍气特征。利用模型AVO演预测莺歌海黄流组含气砂岩的方法及AVO正演曲线及属性剖面的计算原理，了解不同地层状态下岩石储盖组合模型的AVO响应，分析莺歌海盆地黄流组储集层砂岩的含水与含气特征，以预测黄流组储集层的舍气砂岩段。

| Abstract: | The major gas reservoir bed in Yangehai basin is siltstone and fine sandstone. It is difficulty to distinguish directly gas-bearing and water-bearing characteristics of sandstone by common attribute parameters of seismic wave without well-log information. This paper puts forward a method of AVO forward calculation to predict the gas-bearing sandstone in Huangliu Formation,and introduces calculation principle of AVO forward calculation and attribute profile.Geophysical parameter of rocks in this is used in the forward calculation to test the AVO response reservoir rock under different stratum states,the gas-bearing and water-bearing characteristics of sandstone are analysed and the gas-bearing sandstone in the reservior bed of Huangliu Formation is predicted. |
