  Rock Core NMR Device

  August 7, 2020 Blog

  NMR technology can be used to determine the distribution of H proton transverse relaxation time T2 and longitudinal relaxation time T1, which represent the pore structure around spin molecules (such as pore water). NMR technology has been widely used in food, petroleum and soil fields because of its non-destructive and high efficiency. In recent years, rock core NMR device ...

  Rock Core NMR system and Shale

  July 24, 2020 Blog

  Shale has low permeability, low porosity, high clay content and high organic matter content. The lacustrine shale has strong heterogeneity and variable organic matter content. Stratification is a common feature of shale and the main reason for shale heterogeneity. Shale consists of two parts: (a) clay-organic matrix, containing clay minerals and organic matter; (b) inclusio ...

  What can Time-domian NMR do?

  July 16, 2020 Blog

  Time-domain Nuclear magnetic resonance (NMR) is a physical phenomenon in which the nucleus in a static magnetic field is subjected to the electromagnetic wave of the corresponding frequency of another alternating electromagnetic field. After stopping the RF pulse, the nuclei that have transitioned to the high energy state will release the absorbed RF wave energy back to the ...

  What is the data utilization forms of LF-NMR? -Signal amplitude

  July 9, 2020 Blog

  According to the principle of LF-NMR, we know that when the H nucleus is used as the research object, the content of H protons in the sample is proportional to the amount of signal. From a macro perspective, the more mass of the same sample, the stronger the signal. This is the basis of our quantitative research. Before the experiment, we only need to prepare some standard ...

  Low field NMR analyzer and logging

  July 1, 2020 Blog

  Low field NMR analyzer is one of the most prominent new techniques in core analysis and reservoir logging. Although a lot of work has been done in conventional reservoir characteristic analysis, the application of low field NMR analyzer in carbonate reservoir, heavy oil and bitumen formation is still rare. A range of low field NMR analyzers can be used for a range of experi ...
