摘要
V和Ni是石油中的主要微量金属元素,因油藏中存在着向上运移的物质、能量及动力基础,其中的V和Ni也要向油藏上方进行垂向运移并分布在其上方的介质中。用不同方法提取分析土壤、岩屑及地层水中的V和Ni,并根据介质中V和Ni的分布特征可以了解对应地层或下伏地层的含油气性、沉积环境和油源岩质量等地球化学信息。通过在鄂尔多斯盆地镇原—泾川地区进行分析土壤总量V和Ni的实验研究,证实了该方法具有较好的指示油气的意义。
Microelements V and Ni are the main micro metallic element components in the petroleum. Because the material, energy and power foundations of upward migration exist, rnicroelements V and Ni in oil gas pool source migrate vertically above and are distributed in the above environment. Using different methods to extract and analyze the V and the Ni content in soil, rock debris and formation water, we can know the V and Ni distribution characteristics and therefore may understand such information as oiliness in strata or the lower beds, the environment of deposition, the marine or continental deposit, the origin, and the oil source rock quality.
