Abstract: A large number of authigenic pyrites with perfect crystalline were found in the glutenite reservoirs of Jurassic Qigu Formation in Che 60 well field, northwestern margin of Junggar Basin. These pyrites were concentrated in the braided river delta sandbodies with low shale content, high oil saturation and good physical properties. However, strata with pyrite were interpreted as shale intervals in the previous studies based on the well logging interpretation, which directly led to the misunderstanding of sandbody connectivity and remaining oil distri-bution and resulted in the omission of potential oil and gas reserves in the reservoirs. Based on well longing data and core observation, identification charts of pyrite-rich sandbodies were established, and combined with the geologic settings of the study area, 3 D geological modeling technique was applied to establish the formation model of pyrite. And then porosity and pyrite content of the pyrite-rich sandbodies were recalculated through equivalent volume model. The results show that the distribution of pyrite-rich sandbodies was controlled by faults, and pyrite in the glutenite reservoirs could indicate the distribution of oil-bearing sandbodies, and these sandbodies are not shale intervals. The porosity obtained from the equivalent volume model was much closer to the data of core sample analysis than the old interpretation model. These pyrite-rich sandbodies might be the favorable accumulations of remaining oil or potential areas of reserves. This result could enrich the understanding of pyrite and it is significant for the study of remaining oil and the oilfield flooding development.
