Dataset for Different Methods of Permeability Calculation in Thin-Pore Tight Sandstones

The micro x-ray computed tomography images of five clastic tight sandstone samples from one Russian oilfield. General Electric v|tome|x L240 CT system was used to obtain images with spatial resolution 1.2 μm/vox. CT images have size 1400 vox. in each direction. The Manual DIP, Cross-Laboratory Control DIP, and Automated DIP as three different methodologies have been applied to create 3D digital rock models. The number of voxels in the final model, consistency, and consequence of image processing and binarization techniques are the main differences.本数据集包含取自俄罗斯某油田的5块碎屑致密砂岩样品的显微X射线计算机断层成像（micro X-ray Computed Tomography）图像。实验采用通用电气（General Electric）v|tome|x L240 CT系统进行扫描，获取的图像空间分辨率为1.2 μm/体素，各方向的体素数均为1400。本研究通过手动数字图像处理（Manual DIP）、跨实验室对照数字图像处理（Cross-Laboratory Control DIP）与自动数字图像处理（Automated DIP）三种不同方法构建三维数字岩心模型，三者的核心差异体现在最终模型的体素数量、图像处理与二值化技术的一致性及处理结果上。
