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.
