The reservoir properties of the Upper Permian Urho Formation in Well Block Ke81, northwestern margin of the Junggar Basin, exhibit significant heterogeneous characteristics, and there is controversy regarding the attribution of its sedimentary facies. This constitutes a major obstacle to the efficient production of regional oil and gas and the accurate identification of favorable exploration targets.This study comprehensively integrated methods such as core observation, thin section analysis, logging response analysis, and physical property testing to conduct a systematic research on the lithofacies types, reservoir characteristics, and favorable zones of glutenite in the Upper Urho Formation based on hydrodynamic genetic lithofacies classification.The research results show that the glutenite in the Upper Urho Formation in the study area can be classified into two main genetic types: traction current origin and gravity flow origin. Among them, the traction current glutenite is characterized by grain support, positive grading structure, matrix content less than 5%, with an average porosity and permeability of 8.6% and 30.82 mD, respectively. In contrast, the gravity flow glutenite has significantly poorer reservoir properties, featuring matrix support and massive structure, with an average porosity and permeability of only 6.7% and 0.78 mD.By establishing a response model between lithology and electrical logging curves, this study achieved effective identification of different genetic lithofacies. Further verification through reservoir physical property and oil-bearing analysis confirmed that the hydrodynamic conditions during the sedimentary period are the fundamental factor determining reservoir quality, and the concentrated development area of traction current glutenite can be regarded as the sweet spot for the next exploration and development in the study area.
