| 摘 要： | 通过对 19块岩心核磁测量数据的分析 ,发现传统 NMR实验方法确定的 T2 cutoff与理论估计值之间存在着较大误差 ;分析讨论了产生误差的原因 ,提出采用离心法即通过离心束缚水饱和度与全饱和状态下的 T2 分布谱反推求取岩心T2 cutoff的方法。实践证明这种方法是可行的。

| Abstract: | It is found that error between T 2cutoff value from traditional NMR laboratory measurements and the estimated theory T 2cutoff value is larger on the basis of analysing 19 cores NMR data. Causes for the above error is analysed, and further, a new core centrifugal method is proposed to calculate T 2cutoff values. Practice application proves the method is feasible. |
