摘　　要：在湖北宜昌下奥陶统红花园组生物礁中发现并采集到轻质油苗。油苗赋存于碳酸盐岩的成岩裂隙、晶间孔和铸模孔中，其ＲＩＣ谱图清楚反映了烃源岩的海相特征和原油的高成熟性．这一发现对该区油气评价具有积极意义。The oil seepages relative to organic reefs in Yichang,Hubei province were discovered and collected. The oil seepages occurred in diagenetic cracks, intercrystal pores and cast solution pores in carbonate rocks of Honghuayuan Formation (lower Ordovician).Its RIC diagram shows that the oil seepages are characterized by marine factes of oil source rock and by high maturity.This founding is significant to appraisal oil and gas prespecting for Central Yangzi area.
