摘要： 通过对松辽盆地王府凹陷及其周缘地区中浅层原油族组成、轻烃、链烷烃、甾烷、萜烷及稳定碳同位素的地球化学特征的分析,认为该区扶余、杨大城子原油为同一个族群,同时根据原油成熟度的差异,又将其分为3个组群:A区长20井、三403井和五204井分布于古、今构造高部位,为低熟原油,C区双32井位于王府凹陷内,为中等成熟原油,其余组成B区,为低熟-中等成熟原油。

Abstract: The group composition, light hydrocarbon, chain alkane, sterane, hopane and stable carbon isotope are analyzed in geochemical characteristics. Study shows that the crude oils from Fuyu-Yangdachengzi zone belong to the same oil source, which could further be divided into three groups such as immature oil (A) , low-middle mature oil (B) and middle mature oil (C) . Type A is found in Wells Chang-20, San-403 and Wu-204 which are located at the highs of palaeo-and present-structure; Type C in Well Shuang-32 located at Wangfu sag, and Type B is distributed in rest areas.

Key words: Songliao basin, geochemical characteristic, crude oil, maturity
