Abstract:

According to NMR and capillary pressure data, combining jizhong geologic and well test data, well logging interpretation technique is put forward for low resistively reservoir under the condition of complicated geology and reservoir irritable water saturation test method based on NMR logging. By two years application in northern china oil field, the technique can easily and quantitatively evaluate low resistively reservoir resulted from high irritable water saturation, a satisfactory result is achieved.

Key words: resistivity logging, high irritable saturation low resistivity pay zone, logging interpretation, Jizhong
