摘要: 通过甾烷、萜烷、轻烃、含氮化合物等地球化学参数对苏北盆地高邮凹陷北斜坡西部油气成熟度和油气运移进行了研究,得到3点认识:第一,码头庄地区为低-未成熟油,赤岸地区为成熟油,其中韦5和韦8块为生物降解油,两地区的油气分别来自不同油源区;第二,轻烃运移参数显示赤岸地区油气来自邵伯次洼,具自东向西的运移特征;第三,含氮化合物运移参数显示赤岸地区油气运移方向为自东向西,码头庄地区油气则自南向北运移.Abstract: The oil and gas maturity,hydrocarbon migration and accumulation in the west of north slope in Gaoyou Sag are discussed according to such geochemical parameters as steroid,terpane,light hydrocarbon and nitrogen compounds in this paper.Researches show that the oil in Matouzhuang area is low-mature to immature,the oil in Chian area is mature.The oils trapped in Wei 5 Block and Wei 8 Block are biodegraded.The petroleum in the two areas come from different oil sources.The parameters of light hydrocarbon migration show that the hydrocarbon in Chian area comes from Shaobo Subsag.The parameters of nitrogen compounds migration indicate that the hydrocarbons in Chian area migrate from east to west and the hydrocarbons in Matouzhang area migrate from south to north.
