| 摘 要： | 目前核磁共振技术对岩石的孔隙结构进行评价还停留在定性评价阶段。虽然多数核磁实验室开展了核磁共振评价孔隙结构的研究工作，建立了转换模型，但由于转换系数无法有效地确定，还不能进行应用。通过对岩心核磁共振T2谱与压汞孔径分布的对比，建立了转换模型系数与孔渗比的关系，同时考虑了顺磁物质对转换系数的影响，提出了确定转换模型系数的方法，为核磁共振技术进行孔隙结构的定量评价提供了新的方法。

| Abstract: | The NMR technology has been widely used in well logging of oilfields. Up to now, it can only e-valuate the pore structure qualitatively. Although many investigations are concentrated on quantitative research in recent years, the conversion model has not been obtained yet. In this paper we compare T2 distribution with capillary pore distribution, and then establish the relationship between the transformation coefficient and porosity penetrability ratio. At the same time, content of paramagnetic substance is also taken into account. The conversion model is established which is a new method to evaluate the pore structure qualitatively using NMR technology. |
