A New Transformation Method of the T₂ Spectrum Based on Ordered Clustering—A Case Study on the Pore-Throat Utilization Rule of Supercritical CO₂ Flooding in L... by Yanchun Su, Chunhua Zhao, Xianjie Li, Xiujun Wang, Jian Zhang, Bo Huang, Xiaofeng Tian, Mingxi Liu, Kaoping Song

“…For the three kinds of cores with ordinary-low permeability (K > 1 mD), ultra-low permeability (0.1 mD < K < 1 mD), and super-low permeability (K < 0.1 mD), the pore-throat distribution curves of the cores were obtained by using the improved T₂ conversion method. Then, the oil and gas two-phase displacement experiment was carried out to investigate the degree of recovery and cumulative gas–oil ratio changes during the displacement process. …”
