摘　　要：根据王府凹陷岩、油常规地球化学分析、稳定碳同位素和生物标志化合物检测、地层水离子含量、无机物含量、有机组分含量测定，研究青山口组烃源岩的生烃潜能、生烃特征和演化规律，指出青一段泥岩是该凹陷的最有利烃源岩。油源对比结果证实，凹陷内的原油来源于上覆青一段生油岩，自凹陷中心向周边运移，距离不大并有一定的方向选择性。原油与凹陷周边的天然气并非同源。地层水及原油特征表明，王府凹陷同三肇凹陷是两个独立的生油系统。Based on the routine geoehemistry,the stable carbon isotopic compositions and biomarker, the contents of ion, inorganic matter and organic matter in formation water, this paper discussed the potential and characteristics of hydrocarbon generation of source rock from Qingshankuo FM and its evolution, it suggested that the Qing-1 is the best source rock in the sag. Oilsource correlation demonstrates that oil was derived from the source rock of Qing-1 Member, the oil and the gas which surrounds the sag are from different source rocks. The characteristics of formation water and oil indicated that the Wangfu and Sanzhao sags are two independent hydrocarbon generation systems. The oil in the sag migrated from center to edge, but the migration is not long in distance and directional.
