  Analysis of pore permeability of oil-bearing shale assisted by NMR-Part 3

  Febrero 17, 2020 Blog

  Comparison of MRI, CT and SEM Figure 6 CT reconstruction pore distribution, T2 spectrum and helium porosity and permeability measurement The shale nuclear magnetic pore size distribution is in good agreement with the helium porosity, permeability and CT analysis results. See Figure 6. Sample N5-3 has mesopores, with fewer large pores corresponding to medium por ...

  Analysis of pore permeability of oil-bearing shale assisted by NMR-Part 2

  Febrero 10, 2020 Blog

  Shale nuclear magnetic resonance T2 spectrum distribution The T2 spectrum of the core under saturated oil conditions is shown in Figure 2. The T2 spectrum of the shale has three peaks: P1 peak (0.03-1EM), P2 peak (1-20EM), and P3 peak (20-300EM). Sin embargo, the difference between the three peaks in some samples is not obvious, such as samples F41-2, L76-1, N5-3, and Y5 ...

  Analysis of pore permeability of oil-bearing shale assisted by NMR-Part 1

  Enero 17, 2020 Blog

  Introduction· NMR is sensitive to hydrogen-containing materials in porous media and is a non-destructive and effective method for characterizing the physical properties of rocks in oil-bearing reservoirs. Proton nuclear magnetic resonance information is mainly derived from the interaction between protons and magnetic fields, and contains two characteristic time decay con ...
