摘要：

采用三维荧光分析方法,结合芳烃馏分分析结果,对胡庆油田油藏中原油、油砂和烃源岩展开了对比研究。研究结果表明,油藏中原油和油砂的三维荧光光谱具有5种类型,烃源岩存在3种类型光谱特征,所有油藏的主波长低于 Type C类烃源岩,而高于 Type A 和 Type B 类烃源岩。因此确定,广泛分布于胡庆油田二台阶不同断块带的原油是早期成烃旋回期间低成熟、成熟原油混合的结果。

Abstract:

A correlative study was carried out on the crude,oil sands,and source rocks in Huqing oilfield by adopting the 3D fluorescence analysis method and integrating the analysis result of aromatic fractions of crude oil.The result shows that crudes in Huqing oilfield can be divided into 5 types and the source rocks can be classified into 3 types according to their spectrum characteristics.The dominant fluorescence wavelengths of the crude oil samples from all the reservoirs are lower than that of the type C source rocks,but higher than that of the type A and type B source rocks.It is therefore suggested that crudes widely distributed in various fault blocks of Huqing oilfield are the mixture of low-mature and mature oil generated during the early hydrocarbon generating cycle.

Key words: 3-D fluorescene spectrum, fingerprint technology, oil source, Huqing area, Dongp Depression
