摘　　要：运用石油中生物标志物的组成和分布特征 ,在义和庄凸起及其北部斜坡带上区分出了七个不同族群的石油。油 -源对比表明 ,它们分别来自四扣、郭局子、大王北和车西四个生油洼陷的沙四、沙三、沙一段烃源岩。根据成熟度、运移和保存条件等因素的差异 ,每个石油族群可以分为一个或若干个组群。结合区域地质背景 ,指出了义和庄地区油气的运移和聚集方向 。Petroleum at Yihezhuang arch and its northern slope belt is classified seven different families using the constituents and distribution features of its biomarkers. Oil?to?source correlation shows that they come from Es 4, Es 3 and Es 1 hydrocarbon source rocks of Sikou, Guojuzi, Dawangbei and Chexi four oil?generating subsags respectively. Every petroleum family may be divided into one or several groups based on the difference of the factors of maturity, migration, preservation conditions and so on. Direction of oil?gas migration and accumulation at Yihezhuang area are pointed out and the migration boundary of the petroleum is defined in combination with regional geologic background.
