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 C19 tricyclic terpene, C24 tetracyclic terpane,C30 diahopane, C29 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, C27 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.
