METHODS AND SYSTEMS FOR DETERMINING SURFACE RELAXIVITY OF A MEDIUM USING NUCLEAR MAGNETIC RESONANCE |
摘要 |
Methods and systems for determining surface relaxivity from nuclear magnetic resonance measurements relate to applying multiple nuclear magnetic resonance (NMR) diffusion editing Carr-Purcell-Meiboom-Gill (CPMG) pulse sequences to the porous medium, wherein the diffusion editing CPMG pulse sequences have a diffusion encoding time Δ; receiving NMR data generated by the pulse sequences; processing the received NMR data to obtain a distribution ƒ (Τ 2 ,D) for the diffusion encoding time Δ; repeating the applying, the receiving, and the processing at least one time for pulse sequences having different respective diffusion encoding times Δ to obtain respective distributions ƒ (Τ 2 ,D) corresponding respectively to the different diffusion encoding times Δ; and utilizing the respectively obtained distributions ƒ (Τ 2 ,D) to generate a surface relaxivity (p) determination. |
