Lithologic character of Eogene syste is interbedded sandstone and mudstone primarily, including the thin layer oil shale, Neocene- Quaternary system is set of rivers deposits. Based on this, through the reaserch of ateral correlation and distribution characteristics of every structural layers show that: Paleozoic synthem overall thickness of relatively stable.The residual thickness of Mesozoic synthem is difference in the horizontal, Residues in the horizontal thickness of greater difference, to the greatest thickness achieve to 4500m. Eogene syste has obviously fault depression basin deposition characteristic, the thickness of many sags achieve to 3000 m ,from Neocene, the stratum crosswise mop tended to be stable.

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.

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.
可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明:青南凹陷中部的下白垩统烃源岩生油门限深度为4000m(相应的镜质体反射率为0.65%),埋深4000~4400m为低成熟阶段,埋深4400~5200m为成熟生油高峰阶段,因此中沟组烃源岩未成熟,下沟组上部烃源岩低成熟,下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段,赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段,目前尚无烃源岩达过成熟干气阶段。
