我们在研究济阳坳陷第三系原油分类过程中发现,处于基本相同演化成熟阶段的原油却具有不同的烃类类型。我们曾以地层古生物的资料为依据,把它分为水源轻烃油、陆源重烃油和混源中烃油。然而,这一成因类型的探索,目前仅是新的尝试,还缺乏直接的依据。 为探讨这个问题,我们选取了海洋浮游生物、藻类、陆地草本和木本植物、陆地淡水植物及泥炭土等10个样品,进行热压模拟试验,试图探索各烃类类型与生物
In the study of the classification of Tertiary crude oil in the Jiyang depression, we found that the crude oil in the same evolutionary and mature stage has different hydrocarbon types. Based on the data of the paleosol in the strata, we divided it into water-light hydrocarbon oil, ternary heavy hydrocarbon oil and mixed hydrocarbon oil. However, the exploration of this type of causation is only a new attempt at present and lacks a direct basis. In order to explore this issue, we selected 10 samples of marine plankton, algae, terrestrial herbs and woody plants, terrestrial freshwater plants and peat soils, and conducted hot-pressing simulation tests to explore various hydrocarbon types and biological
