摘要

通过自旋回波法测量横向弛豫时间 T2，显示了在模型多孔介质（玻璃珠）中固定流体运动速度的可能性。由于流体和多孔介质的磁导率不同而产生的磁场梯度会导致平均时间 T2 下降，这使得在没有外部磁场梯度的情况下固定流体运动成为可能。在所研究的流体中加入磁性纳米粒子会增加 T2 对流体速度的依赖性，并提高核磁共振-松弛测量法确定多孔介质渗透性的灵敏度。

Control of Fluid Flow Movement in Porous Medium with NMR-Relaxometry Method

The possibility of fixing velocities of fluid motion in model porous medium (glass beads) by measuring the transverse relaxation time T₂ by spin echo method is shown. The magnetic field gradient arising due to the difference in the magnetic permeability of the fluid and the porous medium causes a decrease in the average time T₂, which makes it possible to fix the fluid motion in the absence of an external magnetic field gradient. The addition of magnetic nanoparticles to the fluid under study increases the dependence of T₂ on fluid velocity and increases the sensitivity in determining the permeability of porous medium by NMR-relaxometry.

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
