Biyang Depression is located in the south of Henan Province, and is a typical oil-rich depression in the eastern region. However, previous studies on the characteristics, identification of "sweet spots" intervals, and logging evaluation of continental shale oil reservoirs are relatively weak. In order to clarify the characteristics of shale oil reservoir of the Hetaoyuan Formation in the Biyang Depression and select favorable intervals, the mineral composition, reservoir properties, oil content and other characteristics of shale oil reservoirs in the H3Ⅲ Formation were analyzed based on experimental and logging data. The high-precision logging evaluation model was established for key parameters such as total organic carbon content, porosity, and mobility evaluation parameters. The comprehensive evaluation results show that the burial depth increases, the brittleness, reservoir properties, oil content, and mobility gradually improve, with the bottom of the second layer and the third layer having relatively optimal reservoir quality, and overall have good exploration and development prospects.
