Three periods petroleum accumulation exists in South-of-fifth-area oil field, the first period oil and gas is the Jiamuhe group mature and high mature hydrocarbon and the Fengcheng group mature hydrocarbon in late Permian to early Triassic, was destroyed in the Indo-Chinese movement intermediate stage, but some still is conserved in good conserved condition, which is one of exploration objects. The second period is the Fengcheng group high mature hydrocarbon in late Triassic to early Jurassic, which is the important exploration target. The third period is the Jiamuhe group overmature dry gas in the late Jurassic Period to the early Cretaceous.

五区南油气藏存在三期成藏，第一期是佳木河组过成熟干气和风城组成熟油气，成藏期在晚二叠世到早三叠世，在印支运动中期被破坏了，但是在保存条件好的地区仍存在这一期油气藏，它是勘探的对象之一；第二期是风城组高成熟油气，成藏期在晚三叠世到早侏罗世，也是勘探的对象之一；第三期是佳木河组过成熟干气，成藏期在侏罗纪到早白垩世。

In this paper, the author discovered Solenites murrayana L. et H. from Yaojie Formation of Middle Jurassic which was an important species of Ginkgophytes in Mesozoic during environmental palaeobotany study of Lanzhou-Minhe Basin. The epidermic structure of Solenites murrayana in Yaojie Formation is similar to that of Solenites murrayana in Yorkshire Jurassic of UK by cuticular analyses.

The second group are the mixtures of Jurassic coal-formed oils and Cretaceous-derived oils. The carbon isotope, n-alkanes and isoprenoids compositions of these oils are similar to core extracts from Jurassic coal measures. However, sterane and terpane compositions of these oils show affinity to Cretaceous source rocks. It is deduced that coal-formed oils dissolved the biomarker-rich Cretaceous bitumen of relatively low thermal maturity, and overprinting occurs during oil migration.

第二类原油具有侏罗系煤系烃源岩与白垩系湖相泥质烃源岩混源的特点，这类原油的碳同位素组成、正构烷烃分布特征和姥植比等均表现出煤成油的特征，但甾、萜烷烃类化合物组成与白垩系烃源岩接近，推测是由于侏罗系煤成油在向上运移成藏过程中，受到成熟度相对较低、生物标志物相对丰富的白垩系烃源岩的浸析作用所致。
