| 摘 要： | 在岩性油气藏勘探中，AVO（振幅随偏移距的变化）方法是一种非常有用的油气预测方法。准噶尔盆地阜东地区侏罗系头屯河组河道砂体储集层横向变化快，具有“一砂一藏”的特征，油气预测难度大。在叠前道集正演和流体替换技术的基础上，分析河道砂体和流体的AVO响应，利用AVO叠前属性对阜东地区的5口井进行了预测，取得了很好的地质效果。

| Abstract: | AVO（amplitude versus offset）is a very useful oil?gas prediction method for lithologic reservoir exploration. The Toutunhe channel sand reservoir of Jurassic in Fudong area of Junggar basin is characterized by quick lateral changes and“one sand and one reservoir”, so difficult to properly predict where oil and gas are. In this paper, on the basis of seismic pre?stack gather forward modeling and fluid replacement/alternation, the AVO responses from the channel sands and fluids are studied and the AVO pre?stack attributes are used for oil?gas prediction of five wells in Fudong area. The result shows very good geologic effects |
