摘要
利用Hampson Russell/Geoview/AVO软件研究含气砂岩的地震反射振幅随炮检距的变化关系及AVO属性的特征。并将AVO技术应用于大港油田黄骅坳陷港186井区的天然气藏研究。结果表明,在地质条件复杂的地区,三维AVO分析可区分真假天然气响应,准确确定已知气藏及异常区的空间展布范围。
Dagang gasfield has been processed using 3D seismic data from Hampson-Russell/Geoview/AVO software and has been investigated with AVO technology for detection of gas reservoirs in the Gang-186 well area of Honghu reservoir or Huanghua depression.On the basis of the 3D AVO data,the seismic reflection amplitude varying with offset and AVO attribute properties of gas-bearing sandstone are analyzed.From this study we know that,in the areas of complicated geologic conditions,3D AVO analysis can be used to better distinguish the response of natural gas and determine the spatial distributions of the proved gas reservoirs and the anomalous areas.
