Data for "The Influence of Microporous Cements on the Pore Network Geometry of Natural Sedimentary Rocks"

This folder contains files for pore network modeling of micro CT images for<br>the article "The Influence of Microporous Cements on the Pore Network Geometry<br>of Natural Sedimentary Rocks" by Thomson, Hazel, and Hier-Majumder.<br><br>To create the figures in the article run the python script PNMstats.py<br><br>Description of data:<br><br>The data in Pore_based_only folder uses PNM created only by 'pore-based' mode<br>of PerGeos. For the samples containing microporous cement, the file names 'macro<br>+micro' indicate that the pore space considers the cement phase to be void and<br>treats the porosity prior to cementation. Files marked 'macro_only' considers<br>the microporous cement to be 100% solid. Some other data, with an attempt to assign porosity to the micropores also exist, but they are not used in the article.<br><br>The output of the PNM is saved as two separate files for pores and throats. Open the .csv files to see the headers. There are also data files for Fontainebleau and two Berea sandstones.<br><br><br>

本文件夹包含用于Thomson、Hazel与Hier-Majumder发表的论文《微孔水泥对自然沉积岩孔隙网络几何特征的影响》（The Influence of Microporous Cements on the Pore Network Geometry of Natural Sedimentary Rocks）中显微CT图像孔隙网络建模（PNM, Pore Network Modeling）的相关文件。

若需复现本论文中的全部图表，请运行Python脚本PNMstats.py。

数据说明：

Pore_based_only文件夹内的数据集，采用PerGeos软件的“仅基于孔隙”（pore-based）模式构建孔隙网络模型。对于包含微孔水泥的样本，文件名标注为“macro+micro”的数据集，其孔隙空间将水泥相视为孔隙，并采用胶结前的孔隙度参数；标注为“macro_only”的数据集，则将微孔水泥完全视为固相。另有部分尝试为微孔分配孔隙度的数据集，但未在本论文中使用。

孔隙网络模型的输出结果被分别保存为孔隙与喉道两个独立文件，请打开.csv格式文件查看其表头信息。此外还包含枫丹白露砂岩（Fontainebleau）与两块贝雷砂岩（Berea sandstones）的相关数据文件。
