Online NMR Testing Technology for Real-Time Core Seepage Analysis

The Online NMR Testing Technology utilizes nuclear magnetic core analysis equipment to conduct real-time analysis of physical simulation experiments of core seepage under high temperature and high pressure. This is achieved through the use of nuclear magnetic resonance T2 relaxation spectrum, T1-T2 spectrum, D-T2 spectrum, and 1D / 2D / 3D magnetic resonance imaging. The technology enables monitoring of the fluid distribution of different pore sizes and positions in the core, with the highest experimental pressure being 70 MPa and the highest experimental temperature being 180°C.
