针对胜坨油田W区块储层低孔、低渗、孔隙结构复杂，常规测井方法进行油水层识别和储
层评价难度较大的现状，介绍了利用核磁共振资料T₂谱的分布快速判别流体性质的定性识别方法，与
建立核磁共振测井解释模型、计算储层参数、识别流体性质的定量识别方法，并在胜坨油田W区块低渗
透储层的实际评价中取得了较好的效果。

The reservoir of Shengtuo Oilfield "W" zone has the feature of
low porosity and permeability, and it is difficult to use common
logging program to oil-water reservoir identification and reservoir
evaluate. This paper introduces a qualitative method that uses
distribution of T2 spectrum to identify fluid quality quickly and a
quantitative approach which establishes a nuclear magnetic
resonance interpretation model to compute reservoir parameter, and
other data, to identify fluid quality.The method is applied in "W"low
 permeability reservoir and the result is satisfied.
