| 摘 要： | 过实验室模拟海带的早期成岩作用过程,获得生物改造无定形体样品,观察海带形态变化,测定生化成分、碳氢 氮元素及微量重金属元素含量,为海相底栖宏观藻类的烃源岩形成过程提供现代对比实例。研究结果显示海带在模拟过程 中不断降解,到第 67 天海带细胞已经完全破碎呈无定形体状;微生物促进海带生化成分的转化,厌氧后期多糖和蛋白质含 量下降,粗脂肪含量上升到 8.16%;海带对微量重金属元素有显著的吸附解析作用,使微量元素含量波动变化。早期成岩 过程中微生物改造使海带形态朝无定体转化;有利于脂类成分的增加,利于成烃;元素变化有一定规律,但要直接利用微 量重金属元素进行油源对比可能还存在一些问题,需要进一步研究。

| Abstract: | Amorphous bodies by the transformation of microbial were obtained during the simulation of early diagenesis of kelp in this paper. The morphology of the samples was observed, the content of biochemical components, carbon, hydrogen, nitrogen, and the trace metal elements were determined. The experimental results provided important experimental reference data for hydrocarbon source rocks of marine benthic macroalgae. Kelp was constantly degraded in the simulation experiment, the cells was completely broken as amorphous bodies by the 67th day. The microorganism promoted the transformation of biochemical component. In the late anaerobic stage, the content of polysaccharide and protein decreased, but the crude lipid increased up to 8.16%. Kelp had significant effects on the adsorption of the trace metal elements, and the content of the trace metal elements fluctuated. The results show that the microorganism promotes the transformation of kelp to amorphous bodies, and is beneficial to the increase of lipid and hydrocarbon generation, and the content of elements varied regularly. But there are still problems in using the trace metal elements for oil and source rock correlation directly, So further studies are needed. |
