| 摘 要： | 为预测盐城凹陷含气砂岩的分布范围，利用AVO正演模拟和流体替换等工作取得本地区含气储层的AVO响应特征，并通过该地区关键产气井实际地震资料的AVO分析结果进行验证，再以Zoeppritz方程的Shuey近似表达式为基础，计算出P（截距）和G（梯度）等AVO属性，并通过PG属性进行含气储层的识别，刻画出该区含气砂岩横向和纵向展布特征，结果与实际情况相符。

| Abstract: | To predict the distribution range of gas-bearing sandstone in Yancheng Sag,the AVO responding character-istics of gas-bearing reservoir were obtained by AVO forword modeling and fluid replacement.And the AVO analysis re-sults of the actual seismic data from the key gas producing wells were verified.Based on the Shuey approximate expression for the Zoeppritz equation,it was calculated that AVO attributes including P （ intercept） ,G （ gradient） ,and so on.Finally, based on identification of gas reservoirs by PG attribute,the lateral and longitudinal distribution characteristics of the gas-bearing sandstone were described in this area. |
