| 摘 要： | 准噶尔盆地腹部地区长期以来以二叠系原油的勘探与研究为主。本文在总结本区现已发现侏罗系典型原油地球化学特征的基础上，通过混源油人工配比模拟实验揭示了侏罗系与二叠系原油在混合过程中的典型生物标志物变化特点，提出判识混源油组成的可能标志。据此标准，查清了研究区现有侏罗系原油和油砂的分布特点，再结合侏罗系烃源岩的分布情况，认为本区侏罗系原油可望具有良好的勘探前景，应重视对其勘探和研究。

| Abstract: | In the Central Junggar Basin of northwestern China,in addition to previously reported Permian source derived oils,writers reported the geochemistry of Jurassic source derived oils and further discussed the exploration prospect.Firstly,the geochemistry of oils derived from single Jurassic source rocks was obtained based on GC and GC-MS analytical results.Then,in order to assess the geochemical composition of Jurassic and Permian mixed oils,writers carried out artificial mixing experiments.Combined with previous results,writers suggest the typical biomarker features for differentiating mixed oils.According to these criteria,the occurrence of Jurassic oils and sandstones was unmasked.Subsequently,integrated with the distribution of the Jurassic source rocks in the study area,it is considered that the Jurassic source derived oils have a good prospect,and should be laid more and more emphasis in petroleum exploration and geologic study. |
