| 摘 要： | 采用气相色谱法对渤海海上6个不同区块、7个平台的8口油井原油中正构烷烃组分及姥鲛烷植烷进行了定性定量分析,通过原始指纹谱图、正构烷烃组分及姥鲛炕植烷浓度分布比较和特征比值比较对原油进行了鉴别.结果表明,不同区块的原油指纹信息不尽相同,即使同一平台不同油井所产的原油指纹也存在一定差异,采用气相色谱法进行分析可对其进行鉴别.原油的风化对特征比值影响较小,可利用其进行风化油样的鉴别.为确保鉴别的准确性,分析过程中必须实施严格质量控制措施.

| Abstract: | 8 samples of crude oils coming from 7 different platforms in 6 different oil fields were analyzed by Gas Chromatogram. By using different methods, such as comparison of original fingerprintings, n-alkane characteristic information, and diagnostic ratios, 8 samples of crude oils were identified completely, which showed that the distinction exists in the same platform oils. Although distinguish was diminutive, it can still be identified by Gas Chromatogram. The weathering results of crude oils showed that the stable diagnostic ratios could be used to identify weathered oils, and the unstable diagnostic ratios could be used to check weathering degrees. To ensure accuracy of identification, strict quality control measures were needed. |
