ECS测井及其在西江油田的应用

ECS Well Logging and Its Application in Xijiang Oilfield

在对ECS(地层元素测井)测井资料进行解释时,将元素的相对含量应用氧闭合模型转换成元素含量百分数,进而实现由元素含量到矿物含量的转变。当岩石的成分相对稳定时,岩石中元素含量也基本稳定。如果知道相应元素的百分比,可以实现对储层物性的研究。运用该方法对西江油田的某些井进行处理,得到的结论与试油结论有较好的一致性。

When ECS logging data were interpreted,the relative content of the element was converted to the percentage of element content by using oxygen closure model to realize the transformation from elements content to mineral content.When rock composition was relative stable,the its element content was basically stable.If percentage of the corresponding element was known,the reservoir physical properties could be studied.The method is used for processing some wells in Xijiang Oilfield,the studied result is consistent with the that of formation test.
