油指纹技术在冀东油田溢油鉴别的研究与应用

Research and Application of Oil Fingerprint Technology on Oil Spill Identification in Jidong Oilfield

油指纹是目前溢油鉴别的重要技术手段,随着冀东油田海上开采力度不断加大,该项技术将在污染事故调查中发挥重要作用。监测站运用荧光光谱法对油品的普通、同步、三维荧光进行分析,利用气质联用分析技术(GC-MS)对油品风化前后的生物标记化合物烃类组成开展研究,建立了油指纹数据库。建立一套适用于冀东油田的溢油污染源鉴别的方法,为油田区域多起环境污染事故处理提供了技术支持,而且为日后疑似溢油事件的处理做好基础数据和油样储备。

Fingerprint identification technology is popularly used nowadays as an important technical method for spilled oil identification.As Jidong Oilfield marine crude oil development expanding,the technique will have important practical significance in investigating the oil pollution accidents.The ordinary,synchronous fluorescence spectrometry and three-dimensional fluorescence for oils are analyzed by fluorescence detection,and the hydrocarbon component analysis of the biomarkers of before and after weathered oils is researched with gas chromatographic/mass spectrometric(GC-MS)analysis.On the base of these,oil fingerprint database is established.As an oil spill identification method of Jidong Oilfield is built,it provides the technical support and service to control the oil pollution accidents in oil regions,and has application in handling the suspected oil spill with the collection of the basic data and oils.
