| 摘 要： | 吉林油田红岗北地区部分井区油层电阻率相对较低,对测井油、水层解释造成了困难。利用岩心、测井及试油资料,分析形成低阻油层的主要因素是束缚水含量高,另外地层水矿化度高、淡水泥浆侵入、富含导电矿物等也是造成低阻的原因。因此,利用核磁测井资料建立了束缚水饱和度模型,形成了低阻油层的解释方法及标准,在实际应用中见到了较好的效果。

| Abstract: | The resistivity is lower in the area of north Honggang of Jilin oilfield,so it is difficult to divide the different zones by logging.The prime reason of the low resistivity pay zone is the higher ratio of bound water by explaining of core,logging,wild cat well.Another reason is higher salinity,fresh water invading,much more conducting minerals.So nuclear magnetic image logging data is used to make the model of bound water saturation,it is a method and standard of explaining the low resistivity oil zone.The method is useful in the oilfield. |

| Keywords: | low resistivity oil zone bound water salinity interpretation and evaluation |
