Abstract: Biyang depression in Nanxiang basin is a typical oil-enriched depression in east China.The shale in Hetaoyuan formation is favorable for shale oil and has the characteristics of big thickness,high organic carbon content,developed reservoir space,high brittleness mineral content and abundant hydrocarbon shows.The research results show the continental shale oil enrichement is mainly controlled by shale lithofacies,organic matter abundance,occurrence mode,thermal evolution degree,reservoir physical property,diagenesis and fracture development degree.Resource evaluation results indicate that the Biyang continental shale oil resource is abundant.The 15-level staged fracturing implementation in horizontal well BYHF1 has achieved the highest daily oil production of 23.6 m3,presenting good prospects in biyang continental shale oil exploration and development.
