Research and Analysis of Granite Pore Structure Based on Nuclear Magnetic Resonance
In order to study the characteristics of the internal pore structure of granite,granite from a certain region was selected,and the pro-cessed rock samples were vacuum saturated with water,and the rock samples were detected by NMR testing equipment to obtain the T2 spectro-gram,pore size distribution,porosity and spectral area of the rock.The test results show that:the T2 spectral curve of granite has three peaks,the main peak is around 40,the secondary peak 1 peak is around 52,and the peak area of the two peaks is not much different;granite is domi-nated by small and medium-sized pores,and the large pores are rare;the porosity of granite measured after saturated with water is in the vicin-ity of 1.97%.
