P618.130.2%P744.4; 秦南凹陷经历了 46 年勘探,只发现了秦皇岛 29-2 油气田,尤其是近 9 年勘探无一油气田发现,勘探工作陷入困境.为了弄清秦南凹陷油气成藏主控因素,指明油气勘探方向,利用三维地震、钻井及化验资料,梳理基础石油地质条件,通过已钻井成败分析和类比研究,明确各储盖组合的成藏主控因素,并预测有利勘探方向.研究表明:①秦南凹陷沙三段、沙一段烃源岩发育,TOC为 1.5%～4%,类型为Ⅰ—Ⅱ1 型,资源潜力大,发育潜山、沙河街组-东营组、馆陶组-明下段三套储盖组合.②潜山下组合成藏主控因素为储层非均质性;沙河街-东营组中组合成藏主控因素为圈闭有效性;馆陶-明化镇组上组合成藏主控因素为油源断层的运移能力.③东洼与东南洼间低隆起、东洼西斜坡、东洼和东南洼大断层下降盘...
