| 摘要: |
| 从理论模甩人手，首先研究流体参数变化对地震弹性参数及地震记录的影响，然后用胜利油田某区块的实际 资料进行叠前振幅随角度变化(AVA)弹性反演。在反演基础上,以振幅随炮检距变化(AV0)分析为基础,提取反映 流体特征的不同属性，在剖面与平面上指示出储S流体的特征。反演结果与实际钻井资料吻合率较高，说明叠前反 演与AV0属性分析结合是预测储E流体性质的一种有效方法。 |

| Abstract: |
| The influnce of fluid parameters' variation on seismic elastic parameter and seismic record were researched on the basis of theoretical model. And then prestack amplitude variation with angle(AVA) elasticity inversion was carried out by using Shengli block's real data. Based on inversion and amplitude variation with offset (A VO) analysis, different attributes of fluid characteristic were extracted and reservoir fluid characteristics on profile and plane were predicted. The inversion results agree well with reai well-drilling data, which shows that the combination of prestack inversion and AVO attribute analysis is an effective method of reservoir fluid prediction. |
