摘　　要：综合运用有机地球化学方法,对哈山地区及周边油样进行分析,以确定该区的稠油特征及成因,为下步滚动勘探开发指明方向。结果表明:该区原油密度和黏度在平面上具有"北高南低、西高东低"的特点,纵向上由深到浅原油物性及族组成特征有变差趋势。通过原油饱和烃气相色谱、轻组分色谱峰、萜类、萘系列化合物、三芳甾烷系列化合物、芳烃生物标志物、咔唑类及其他生物标志化合物的含量变化等综合分析,认为该区稠油成因复杂,是生物降解、氧化、水洗、逸散及二次充注综合作用的结果。二次充注发育、散失作用弱的区域为滚动勘探开发的有利区域。有机地球化学研究方法对研究复杂稠油的成因具有重要的参考意义。Organic geochemical test is used to analyze the oil samples in Hashan and surrounding areas. The heavy-oil properties and genesis are researched to provide further guidance for the further rolling exploration and development. Research shows that the plane oil density and viscosity are featured by'high in north and lower in south,higher in west and lower in east'. The oil properties and group composition indicate a descending trend from deep to shallow in the longitudinal direction. The comprehensive analysis of content variations in oil saturated hydrocarbon by gas chromatography,chromatographic peak of light component,terpenes,naphthalene compound,triaromatic steroid compound,aromatic hydrocarbon biomarkers,carbazoles and other biomarkers indicates that the heavy-oil with complex geneses in this area mainly results from the combined actions of biological degradation,oxidation,washing,effusion and second charging. The areas with better secondary charging and weak dissipation are considered as favorable areas for rolling exploration and development. Organic geochemical analysis could provide certain reference for genesis analysis of complex heavy-oil.
