摘　　要：青南洼陷是济阳坳陷勘探程度较低的地区之一。首先以地质研究为基础,分析地层和沉积演化特征,其次从生油岩评价、储集层研究和生储盖组合等方面,详细论述了青南洼陷的成藏条件,指出该区具有E_2s_3、E_2s_4“双油源”的有利条件;发育多套储集体和3种生储盖组合类型,形成多种类型的油气藏;提出了在南、北两个斜坡带近期可供钻探的有利目标,为胜利油区今后的可持续发展打下良好的基础。Qingnan low land is one of the areas with low degree of prospecting in Jiyang depression. First, formation and sedimentary evolution are analyzed on the basis of geological study. Second, reservoir forming conditions of Qingnan low land are discussed in aspects of source rock, reservoir and source - reservoir - caprock assemblage. It has been pointed out that this area has double oil sources' of E2s3 and E2s4. This area had developed many reservoirs and three source - reservoir - caprock assemblages, resulting in various oil and gas pools. Drilling targets on the south and north slope zone in the near future are proposed, thus providing basis for future continuous development of Shengli oilfield.
