西西伯利亚巨型含油气盆地侏罗系有机质的成熟度取决于地层的埋深和这一时期它所经受的最高温度。沉积盖层中的温度分布与古生代基底局部断块的褶皱时代、深大断裂的形成时间,以及岩浆岩的成分、侵入时间有关。这些控制着温度场和西西伯利亚沉积盖层中有机质成熟度的因素是全球性的。划分出了3种基本的断块类型,它们与根据基底固结时代而划分的构造区划相对应。第1类断块与贝加尔褶皱带的断块相一致;第2类断块与海西运动期、加里东运动期的断块相一致;第3类断块为巨型盆地基底中的三叠纪裂谷,大型花岗岩体、某些流体输导断裂与此相一致。
The maturity of Jurassic organic matter in the West Siberia giant petroliferous basins depends on the depth of the formation and the maximum temperatures it experiences during this period. The temperature distribution in the sedimentary cover is related to the fold age of the local fault blocks in the Paleozoic basins, the formation time of deep faults, the composition of magmatic rocks and the time of intrusion. These factors controlling the temperature field and maturity of organic matter in the sedimentary cover of West Siberia are global. Three basic types of fault blocks have been identified, corresponding to the tectonic divisions divided according to the age of the substrate consolidation. The first type of fault block is consistent with the fault block in the Baikal fold belt; the second type fault block is consistent with Hercynian and Caledonian fault blocks; the third type is the Triassic in the basement of the Jurassic Basin Rift, large-scale granite bodies, some of the fluid-bearing faults consistent with this.
