From the angle of refinement, nondestructive and quantitative characterization, NMR and CT scanning techniques were used for shale reservoir of pore structure. The results show that: ①The shale T2 spectrum as the asymmetric continuous double peak structure, no single peak T2 spectrum, spectral peak is the peak representing the development of pores; ② The shale micro pore, micro cracks is in the minimum density, CT in gray image is black, gray image by pseudo color enhancement, can more directly observe of shale internal porosity characteristics; ③ The three tuple shale structure, minerals, organic components and pore are of different CT number and CT distribution interval, CT number of pores are usually less than 300 HU, so it can be through the CT number to quantitatively identify pore; ④According to the shale NMR resonance experiment T2 cutoff value of the effective porosity calculation of shale, mobile fluid percent in shale reservoirs was analyzed.
Key words： Shale gas; Doushantuo Formation; Pore structure; CT number.
