叠前地震预测储层的含气性
|
摘要
就叠前地震储层预测而言,AVO方法的应用可分作两个部分:一是以测井资料为基础,基于地震反射原理通过AVO正演模拟来研究含气储层的AVO异常响应特征,并以此为依据指导对基于叠前地震资料反演AVO异常属性的解释;二是基于叠前地震资料进行AVO反演,提取AVO异常属性参数,基于泊松比和流体因子特征来预测储层的分布和含气性状况。
On pre-stack seismic reservoir prediction is concerned,AVO application can be grouped into two parts: One is to study the gas-bearing reservoir in response to the unusual characteristics of the AVO based on log data on seismic reflection through the AVO forward modeling.And using it as the basis for guidance inversion AVO anomalies to explain the properties based on the pre-stack seismic data;Second,proceeding AVO inversion based on pre-stack seismic data,and Extracting AVO abnormal attribute parameters,based on Poisson's Ratio and Fluid Factor to predict distribution of reservoir and gas-bearing status.
