Abstract：In order to find out the characteristics and influencing factors of shale oil reservoir in the lower third member of Shahejie Formation of Paleogene in Luojia area of Zhanhua sag, the authors studied the lithology, space type, influencing factors and evaluation parameters of shale oil reservoir by comprehensive analysis of cores, thin sections, SEM and so on. The results show that mineral composition and sedimentary structure are two important factors, based on which the shale oil reservoir can be divided into seven types. The reservoir space of different lithological types varies greatly. Laminated argillaceous limestone and limestone reservoirs were mostly developed, and laminated gray mudstone reservoirs were relatively developed, followed by massive mudstone. The massive argillaceous limestone, massive grey mudstone and laminated siltstone reservoirs were less developed. The reservoir space of shale oil reservoir in the study area was mainly influenced by mineral composition, sedimentary structure, organic matter content and occurrence mode as well as diagenesis. On this basis, calcite content, laminar structure, TOC content, Ro and porosity were selected as evaluation parameters and the shale reservoir in Luojia area of Zhanhua sag was classified into three types: high quality reservoir, favorable reservoir and unfavorable reservoir.
