Novel stress sensitivity of pore-size distribution based porosity-permeability models in unconventional rocks

Our data show the sevolution of stress-dependent porosity, permeability and T2 distribution of the sandstone and shale samples. Novel stress sensitivity models considering PSD, McKee’s models and Schlumberger-Doll-Research model are employed, and their prediction accuracies are compared.

本数据集展示了砂岩与页岩样本在应力依赖性孔隙率、渗透率以及T2分布方面的演化趋势。本研究采用考虑了PSD、McKee模型以及Schlumberger-Doll-Research模型的应力敏感性新型模型，并对它们的预测精度进行了比较。
