摘要

摘要: 烃源岩的孔隙度为其成烃空间,当烃源岩孔隙空间充满油时才能发生有效排油.依据渤海湾盆地东营凹陷有效泥质油源岩孔隙度与成熟度和密度之间关系模式,结合不同类型烃源岩热演化生油气过程中有机碳转化率,对东营凹陷有效泥质油源岩有机碳丰度评价标准进行了研究.结果表明,不同类型、不同成熟阶段的有效泥质油源岩,其有机碳丰度评价标准差异很大,其中Ⅰ,Ⅱ型有效泥质油源岩的总有机碳丰度最低下限值分别为2.01%和3.51%,残余有机碳丰度最低下限值分别为0.57%和2.07%.

Abstract: The porosity of source rock is its hydrocarbon generating space.When the pore space of source rock is fully filled by oil,the oil can be discharged effectively from source rock.According to the relationship model of porosity between thermal maturity and density for effective muddy oil source rocks from the Dongying Sag and combined with the relationship between maturity and organic carbon rate of conversion for source rocks of various types,the appraising standard of organic carbon abundance for the effective muddy oil source rocks from the Dongying Sag has been studied.The results show that appraising standard of organic carbon abundance for the effective muddy oil source rocks is great difference.The lowest values of total organic carbon abundance for effective muddy oil source rock with type Ⅰand Ⅱ are 2.01% and 3.51% respectively,and the residual organic carbon abundance for effective muddy oil source rock with typeⅠ and Ⅱ are 0.57% and 2.07% respectively.
