摘要
岩石孔隙中流体的核磁共振行为与自由状态下的流体很不相同，前者由于受到固液界面效应和孔隙形状等多种因素的影响，出现核磁共振谱线增宽，驰豫显著加快等。作者利用分辨、固体魔角旋转、显微成象、脉冲场梯度等核磁共振新技术，系统地研究了岩石核磁共振特性。探讨和发展了对岩石样品的内部结构，储集参数及渗流特性等进行定性和定量描述的方法。利用核磁共振进行岩心分析，核磁共振测井等也进行了探讨。
The NMR of fluids in porous rocks are obviously different from that in thebulk fluids, in the former case the NMR lines are widely broadened while the relaxation time is quickened. The mechanisms for line broadening and relaxation quickening are investigated in detail. With the applications of liquid state high resolution, solid state magic angle spinning, microscopy, and pulse field gradient NMRnew technology, the NMR properties of rock samples are systematically studied.Qualitative and quantitative methods for rock description are developed. In addition, the applications, such as NMR core analysis, NMR well logging, NMR inEOR etc, are discussed.
