According to the NMR spectroscopy of fluids saturated 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 visualized. The images can provide detailed discription of the distribution of the internal porosity of the rock samples.

Key words: NMR microscopy, Spin density image, Rock sample, Porosity distribution
