| 摘 要： | 准噶尔盆地西北缘五-八区具有构造高部位为气藏,中部位为稠油油藏,低部位为稀油油藏的分布规律.天然气的地化特征表明:其成因类型可分为油型气、混合气和煤型气.储层沥青的生物标志物表明,乌尔禾组(P2w)储层沥青普遍遭受了生物降解作用,克下组(T)21储层沥青具有与稀油一致的指纹特征,佳木河组(P1j)储层沥青则表现了原生烃特征.结合地质条件,探讨了油气运移及聚集史

| Abstract: | The distrbution of gas reservoirs in 5-8 region of northwestern margin of Junggar basinare that gas in the high of structures,heavy oil in the middle of structures and thin oil in thelow of Structures.The geochemical characteristics of gas indicated that the gas in the regioncomprised of oil-Aerived gas,mixture gas and coal-derived gas.The biomarker of reservoirasphalt indicates that the Triassic and the Permian in the region were migration pathes for oiland gas,in which the asphalt in Wuerhe group reservoir(P2w) underwent generallybiodegradation,the characteristics of the asphalt in reservoirs in low Karamay group(T21)isthe same with oils,the asphalt in Jiamuhe group had characteristics of primary hydrocarbon. |
