低场核磁共振岩心分析及其在测井解释中的应用

Low Field NMR Core Analysis and Its Applications in Log Analysis.

文中介绍低场核磁共振（ＮＭＲ）岩心分析方法，包括测量原理，数据处理及实验步骤。深入讨论了ＮＭＲ测井解释模型，包括孔隙度、束缚水及渗透率方程的建立过程。利用ＣｏｒｅＳｐｅｃ－１０００岩心分析装置，对中国某区块的岩样进行了分析处理，建立了该地区的ＮＭＲ测井解释模型与基本响应方程。

Low field NMR core analysis methodology, including measurement principle, data processing and experimental procedure, is introduced in this paper. Interpretation models for NMR logging, such as the models for porosity, irreducible water and permeability, are discussed in detail. With a CoreSpec 1000 core analyzer, various NMR interpretation models and basic response equations for certain blocks in China are established.
