摘　　要：对准噶尔盆地三台-北三台及吉木萨尔地区原油样品分析发现,二萜类烷烃中二环倍半萜含量丰富。二环倍半萜分布特征显示,该区原油分为三类,A类原油补身烷含量相对较高,重排补身烷/8β(H)-补身烷比值小于0.6;B类原油的重排补身烷的含量与补身烷含量相当,两者比值为0.8～1.1;C类原油的重排补身烷含量相对较高,重排补身烷/8β(H)-补身烷比值大于1.1.二环倍半萜分布特征表明,东部A类、B类和C类原油属于不同的成因类型。The analysis of crude samples from Santai-Beisantai and Jimusaer areas in Junggar basin shows that the bicyclic sesquiterpenoids are rich in the diterpenoid alkanes. From the bicyclic sesquiterpenoids' characteristics, the crude oils from these areas could be classified into three types: Type-A is of high contents of drimanes in terms of the ratio of rearranged drimane/8β(H)-drimane of 0.6; Type-B ranges from 0.8 to 1.1; Type-C is bigger than 1.1in this ratio. It is indicated that the three types of crude oils belong to different types of origins based on the distribution of dicyclic sesquiterpenoids.
