In recent years, the glutenite reservoirs are the hot spots of oil and gas exploration. However, the glutenite has various lithologic types, diverse rock components, complex pore structure and strong reservoir heterogeneity, which makes it difficult to accurately calculate the reservoir permeability. Permeability is an important parameter in the later development of reservoir. In order to accurately calculate the permeability of glutenite reservoir, taking the glutenite in the upper fourth member of Shahejie Formation in the northern steep of DX Sag as an example, the lithology and physical properties of the reservoir are analyzed and summarized by comprehensive utilization of logging, core description, scanning electron microscope and other data. On this basis, lithology classification, theoretical derivation and multiple regression methods are used to establish the permeability calculation model of glutenite reservoir, and three types of permeability calculation models are obtained. The advantages and disadvantages of different interpretation models and their causes are compared. The calculation model by theoretical derivation has the highest correlation coefficient (R2=0.9), but the logarithmic regression formula (R2=0.88) has better applicability.
