The application of seismic oil-water identification method to Guantao Formation of Bohai S oil field

  • 受限于地震资料分辨率较低,渤海S油田馆陶组的复合叠置砂体中的单砂体顶底识别较困难;且在时—空域里,地震反射特征相似的砂层组出现截然不同的流体类型,油水关系非常复杂。为此,本文首先开展了反褶积广义S变换的时频分析,参照已钻井的地震反射特征,优选低频、高频属性体;其次进行储层顶、底的准确识别;利用双相介质理论进行油、水的频谱特征差异分析。分析表明,油、水层在频率域的地震响应有较明显的特征,频率类的属性对地震波的高频衰减较敏感;通过优选该油田主力油层的低频、高频属性体数据及储层顶、底的频谱衰减差异的平面数据,共同构建一个新的流体识别因子,进行油水识别,并取得较好的效果,助力剩余10余口开发井的布署和实施。
