介绍了一种利用核磁测井资料建立束缚水体积模型的新方法。
A new method for establishing bound water volume with NMR logging data is introduced.
核磁测井是当代唯一能够直接测量油层自由流体孔隙度的高技术。
Nuclear magnetic logging is a high technology and only by which the free fluid porosity of an oil-bearing bed can be measured directly.
但是，在我国部分油田的应用中发现核磁测井孔隙度与常规孔隙度之间存在明显差异。
However, it is found that porosity difference between NMR and conventional porosity logging is unacceptable in some oilfields in China.
火成岩具有强磁化率，导致火成岩孔隙内部产生强磁场梯度，使火成岩的核磁测井T2谱发生前移、核磁孔隙度减小；
Igneous rock with strong magnetic susceptibility, leading to strong internal magnetic field gradient, and to T2 spectrum forward and NMR porosity decrease.
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。
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 …
