  Study on Improving Recovery Efficiency of Shale Carbon Dioxide Miscible Flooding-Part 2

  April 3, 2020 Blog

  Results The Benchtop NMR T2 spectrum distribution curve of the carbon dioxide miscible flooding process is shown in Figure 5. Under the same parameter, the signal intensity is positively related to the number of protons or molecules. The signal intensity reflects the amount of n-dodecane in the sample. Because n-dodecane was replaced by carbon dioxide, the T2 spectrum di ...

  Study on Improving Recovery Efficiency of Shale Carbon Dioxide Miscible Flooding-Part 1

  March 26, 2020 Blog

  Introduction 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) a clay-organic matrix containing clay minerals and organic ma ...

  Review: Review the microwave response of starch structure from the perspective of dielectric properties

  March 20, 2020 Blog

  Introduction The dielectric properties, wave absorbing properties and related electromagnetic indicators of different starchy materials are reviewed. The possible structural changes of starch in the microwave field (apparent morphology, sheet structure, crystallization, etc.) are analyzed step by step from macro to micro. Structure, molecular chain structure, etc.), tryi ...

  Discussion 1 .The peak change of nuclear magnetic spectrum of water The first is the change in the spectral peak of water. From S2 to S3, only peak P1 with relaxation time between 0.1ms and 10ms appeared, which was caused by water molecules evaporated from the solution diffusing into the coal and finally adsorbed in the tiny pores. Since S4, peak P2 with a relaxation ...
