| 摘 要： | 通过典型原油混合实验及其产物的地球化学剖析,揭示当煤成油和下第三系原油混合时,随着下第三系原油的增加,C19三环萜烷,C24四环萜烷,C30重排藿烷,C29甾烷和重排甾烷逐渐变小;而姥鲛烷和植烷,伽马蜡烷和C27甾烷含量则逐渐增加。利用饱和烃生物标志物和芳烃化合物绝对浓度的变化规律,建立了冀中坳陷苏桥-文安地区混源油定量识别模式图版。根据混源油识别的模式,判断苏49井的混源油是由10%的下第三系原油和90%的煤成油混合而成;相反文1021井混源油则是由90%的下第三系原油和10%的煤成油混合而成。

| Abstract: | Artificial mixed experiment and geochemical characteristics of mixed oils between coal formed oil and Paleocene Tertiary oil from Suqiao-Wenan Area in Jidong Depression have been analyzed and studied systematically, the results suggest that the absolute amounts of C 19 tricyclic terpene , C 24 tetracyclic terpane ,C 30 diahopane, C 29 sterane and diasteranes are decreasing due to the increasing of Paleocene Tertiary oil in mixed oils. In contrast, the absolute amounts of pristane, phytane , gammacerane, C 27 sterane are increasing. Quantitative identification model of mixed oils from Suqiao wenan area in Jidong depression have been established based on geochemical characteristics of the absolute amounts for saturated hydrocarbon biomarkers and polycyclic aromatic hydrocarbons. According to the geochemical model of our study, crude oil of Well Su 49 consists of approximately 10% Paleocene Tertiary oil and 90% coal formed oil, and the crude oil of Well Wen102 1 consists of approximately 90% Paleocene Tertiary oil and 10% coal formed oil. |
