| 摘 要： | 运用钌离子催化氧化技术(RICO)研究了渤海湾盆地东营凹陷草桥油田生物降解原油沥青质.原油沥青质RICO产物主要包括一元酸、二元酸、三环萜烷酸、藿烷酸、伽马蜡烷酸、孕甾烷酸、甾烷酸等,键合在沥青质芳核结构中的生物标志物以特定碳位与沥青质结合.草桥生物降解原油沥青质RICO产物中具有较高的伽马蜡烷酸/C30藿烷酸比值,具有完整的4-甲基、4,4-二甲基甾烷酸系列,表明原油为沙四段、沙三段的混源油;生标酸异构化参数低表明原油成熟度不高.沥青质钌离子催化氧化技术对于强烈生物降解原油的油-油对比、油-源对比提供了一种新的途径.

| Abstract: | The asphaltene of a biodegraded oil from Caoqiao oilfield, Dongying depression, Bohaiwan Basin has been investigated by ruthenium-ions-catalyzed oxidation technique (RICO). The products of asphaltene RICO included n-alkanoic acids, dialkanoic acids, tricyclic terpernoid acids, hopanoic acids, gammacerane carboxylic acids, pregnanoic acids, sterane carboxylic acids and so on . The biomarkers were bounded on the asphaltene with specific carbon position respectively. The high ratios of gammacerane carboxylic acids to C_ 30 hopanoic carboxylic acids and a complete series of 4-methyl, 4,4-dimethyl steranoic acids indicated that the oil is a mixing oil originated from Es4 and Es3 source rock. The low isomerization of the biomarker acids showed that the maturity of the oil is low. Ruthenium-ions-catalyzed oxidation of the asphaltene provided a new pathway for the oil-oil correlation and oil-source correlation of heavily biodegraded oil. |
