高束缚水饱和度低阻油层测井解释技术

HIGH IRRITABLE WATERS SATURATION AND LOW RESISTIVELY RESERVOIR LOGGING INTERPRETATION TECHNIQUE

依据室内核磁共振、毛管压力等多项实验分析资料 ,结合冀中地质实际、测井、试油资料 ,提出了基于核磁共振测井的储层束缚水饱和度校验方法和复杂地质条件下低电阻率油层测井解释技术。经过近两年在华北油田的实际应用 ,利用此技术可方便地定量评价由高束缚水饱和度引起的低电阻率油层 。

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.
