综合利用核磁谱差分与谱位移测井提高油层解释精度

Integration of NMR DTW Logs and DTE Logs to Improve the Oilbed Interpretation Accuracy.

以辽河油田应用实例分析了核磁谱差分测井在油气层解释识别应用中的多解性 ,提出综合利用核磁谱差分及谱位移测井减少核磁测井烃检测多解性 ,提高测井解释精度的观点以及解释分析方法 。

In this paper, some limitations are analyzed in oilbed identification by using single NMR hydrocarbon detection log, such as DTW or DTE log. A comprehensive interpretation method is provided for discriminating oilbed and waterbed by utilizing integrated DTW and DTE or EDM NMR logs. Some log examples in Liaohe Oilfield and other oilfields are also given in this paper.
