According to the relations of pixel signal intensity with the repetition time T_R and echo time T_E in spin-echo single slice imaging pulse sequence, by combining the multi-exponential relaxation procedure of fluids saturated in porous media, tlle information about pore structure of the tested rock is obtained with T_1- and T_2-weighted microimagings. The macro- and micro-pore regions can be distinguished with the information.
