Hydrocarbon Source Rock Evolution Patterns of Coal-Oil Associated Basins
-
摘要: 在辽河外围众多的晚中生代断陷盆地中,不同类型的盆地(单旋回或双旋回)其烃源岩演化特征各不相同。本文针对不同类型盆中的烃源岩,运用盆地模拟技术,通过分析烃源岩演化曲线,提出了烃源岩的三种演化模式,并依此分析了相应模式下的成藏特点。Abstract: The evolution feature of hydrocarbon source rocks are different with various types(mono cycledouble cycles) of rift basins of Late Mesozoic in the peripheral area of Liaohe Basin. Based upon the hy-drocarbon source rocks of different types of basins, their evolution curve was analyzed through basinmodelling. Three evolution patterns were raised and the oil reservoir characteristics under different pat-terns were discussed as well.
