摘要
According to the NMR spectroscopy of fiulds satuxated in porous rocks, by using different pulse sequences and imaging parameters, high resolution NMR micro-images of lime stone and sand stone samples were obtained. The heterogeneous interconnection structure of the tested sandstone is visuallzed. The images can provide detailed discription of the distribution of the internal porosity of the rock samples.
