苏北盆地管镇次凹陷阜四段烃源岩属低熟烃源岩（Ｒ０≤０．７％）。在重建该套烃源岩埋藏史和地热史并应用其干酪根Ｃ／Ｓ原子比确定其有机质化学动力学类型和相应的化学动力学参数的基础上，对该套烃源岩的生烃史和排烃史进行了模拟。结果表明，阜四段烃源岩分别在始新世中晚期和渐新世早期进入了生烃期和排烃期。综合地质、油源地球化学资料的研究表明，阜四段低熟烃源岩含油气系统为一个未完成的、目前仍处于持续阶段的含油气系统。该含油气系统的原油具有低熟油的特征。阜四段烃源岩的低成熟和低含油饱和度，且进入排烃期后未经进一步的压实作用，导致该套烃源岩的排烃效率较低，进而造成该含油气系统的油源不足。此外，该区主要断层（管镇断裂）对油气运移起隔挡作用，油气二次运移的距离短，因此，该含油气系统受管镇断裂的控制，其区域展布局限在管镇断裂靠油源的东南一侧。
The source rocks of the Fu-4 member of Guanzeng sub-depression of Subei Basin belong to low maturity source rocks (R0≤0.7%). Based on the reconstruction of the burial history and geothermal history of the source rocks and the determination of their organic chemical kinetic types and their corresponding chemical kinetic parameters by the kerogen C / S atomic ratio, the hydrocarbon generation history of the set of source rocks And hydrocarbon expulsion history were simulated. The results show that the source rocks of the fourth member of the Fuxian Formation have entered the hydrocarbon generation period and the hydrocarbon expulsion period respectively in the middle and late Eocene and early Oligocene. Based on the comprehensive geology and oil geochemistry data, the oil and gas system of low-maturity source rocks in Fu 4 Member is an unfinished petroleum system that is still in the continuous stage. The petroleum-bearing crude oil is characterized by low cooking oil. The low maturity and low oil saturation of the source rocks of the F4 Member and their subsequent compaction after entering the hydrocarbon expulsion period led to the lower hydrocarbon expulsion efficiency of the source rocks of the set, Insufficient source. In addition, the major faults in the area (Guanzhen fault) function as a barrier to hydrocarbon migration and have a short distance of secondary migration. As a result, the petroleum system is controlled by the fault of Guanzhen and its regional distribution is limited to Guanzhen Break the oil southeast side of the source.
