| 摘 要： | 由于稠油有较短的T2谱,常常达到束缚流体的范围,所以对于稠油层,核磁共振测井表现为异常高的束缚水饱和度和很低的核磁渗透率,并且核磁渗透率随地层稠油饱和度的降低而增加,束缚水饱和度随地层稠油饱和度的降低而降低。因此,可以把核磁渗透率及束缚水饱和度结合起来判断稠油水淹。

| Abstract: | Because T2 spectra of thick oil are shorter and can rich the range of bound fluids, nuclear magnetic resonance logging in thick oil zones appears abnormally high bound water saturation and low permeability. The permeability increases as the saturation of thick oil decreases, and the bound water saturation decreases as the saturation of thick oil does. Therefore, the water-flooded zones of thick oil can be judged according lo the combination of the permeability and bound water saturation of NMR. |
