| 摘 要： | 核磁共振测井具有常规测井无法比拟的优势，它可直观准确地提供储集层的孔隙度、渗透率，区分可动流体和束缚流体．根据差谱分析可以定性的识别油水层．通过求解地层的束缚流体饱和度，结合电阻率测井，采用阿尔奇饱和度解释模型，进行了油(气)层的识别和含油(气)饱和度的计算，从而拓宽了核磁共振测井资料的应用范围，为低孔低渗油(气)层的评价提供了一种新的途径．

| Abstract: | Magnetic Resonance Image Log (MRIL) has significant advantage over conventional well logs, which can provide accurately porosity and permeability of reservoir as well as distinguish movable fliud and irreducible or bound fliud. The oil or water zone can be qualitatively identified by using spectra difference. Finally , this paper presents results for recognition of oil and gas zone,and saturation estimation by solving irreducible fliud saturation and combining resistivity logging with Archies saturation interpretation model, these studies expend scope of using MRILs data, which also provide a new technique for evaluation of low porosity and permeability oil or gas reservior. |
