A review on pore structure characterization in tight sandstones
Jin Lai,Guiwen Wang,Ziyuan Wang,Jing Chen,Xiaojiao Pang,Shuchen Wang,Zhenglong Zhou,Zhibo He,Ziqiang Qin,Xuqiang Fan +9 more
TL;DR: In this paper, the pore size distribution and 3D pore connectivity are evaluated from NMR and XCT analysis, and the NMR spectrum is also linked to the macroscopic performance, and pore network is determined from N 2 GA, and fractal theory is introduced to explain the irregularity and heterogeneity of pore throat structure characteristics.
