近年来的研究证明 ,中新生代未熟 -低熟海相富有机质泥质烃源岩中有机质是通过溶解在水中的分子规模的碳有机质以化学吸附的形式被吸附到矿物表面上和蒙脱石结构层内 .然而 ,对于高熟海相泥质烃源岩中有机质的赋存状态却少有报道 .通过对塔里木盆地下寒统底部高熟海相泥质烃源岩的有机碳含量、矿物表面积、扫描电镜和透射电镜的综合分析 ,得到了其有机质以细小的颗粒状保存于沉积物颗粒之间的结论 .同时 ,通过高熟海相烃源岩与现代未熟海相烃源岩有机质赋存状态的对比 ,提出了值得进一步研究的有关科学问题 .
In recent years, studies have shown that the organic matter in the Meso-Cenozoic immature-low maturity marine organic-rich muddy source rocks is adsorbed onto the surface of minerals by the chemical adsorption of molecular-scale carbon and organic matter dissolved in water. However, few reports have been made on the occurrence of organic matter in the mature mudstone source rocks in the high-maturity.According to the organic carbon content of the mature mudstone source rocks at the bottom of the Lower Oligocene in the Tarim Basin, Surface area, scanning electron microscopy and transmission electron microscopy, the conclusion was obtained that the organic matter was deposited in fine granular form between the sedimentary grains.At the same time, through the combination of high-mature marine source rock and modern immature marine source rock organic matter Contrasting the state, put forward the scientific issues worthy of further study.
