围绕海相烃源岩,特别是碳酸盐岩的有机质丰度下限标准的讨论,到目前尚无统一定论。弄清楚海相烃源岩有机质丰度的影响因素,可以更准确地确定其下限标准,有助于正确认识烃源岩的成因及分布,为评价有利烃源岩提供科学依据,具有十分重要的理论意义和实际的勘探价值。 Discussion of the lower limit of organic matter abundance surrounding marine source rocks, especially carbonate rocks, has not been concluded yet. Understanding the influencing factors of organic matter abundance in marine source rock can determine its lower limit standard more accurately, which is helpful to correctly understand the genesis and distribution of source rock. It is very important to provide a scientific basis for evaluating favorable source rock Theoretical significance and practical exploration value.
