By using field emission scanning electron microscope, this paper observed and described the size, shape, distribution and seepage characteristics of micropore in dark shale in northern and northwestern Guizhou. Based on the genesis, the pores were divided into three categories: primary sedimentary pores, secondary pores and mixed pores. Based on the development location, the pores were divided into ten sub-categories, such as intergranular pores, intra- crystalline pores, fossiliferous pores, organic matter pores and so on. The influencing factors for the pore development and the pore evolution characteristics of shale were discussed, which has important theoretical and practical significance forthestudyonshalereservoir.
