摘　　要：奥陶系碳酸盐岩潜山是黄骅坳陷主要勘探领域之一,也是较为独特、成因复杂的勘探对象。以千米桥、港西、孔西及乌马营等潜山为例,在应用前人研究成果的基础上,系统分析潜山成藏理论,研究了黄骅坳陷奥陶系潜山的构造演化、圈闭类型、储层特征、烃源岩的形成演化以及时空配置关系,在"新生古储"和"古生古储"2类成藏分类的前提下,结合潜山的发育部位、构造样式、供储方式和成藏作用等因素,建立并完善了该区反转逆冲断块"新生古储"、盆内高位断块"新生古储"、盆缘高位残丘山、反转逆冲断块"古生古储"及深埋逆冲断块"古生古储"5种潜山成藏模式。Ordovician carbonate buried hills are important,distinctive and complex exploring and researching areas in Huanghua Depression. Based onthe others' conclusions and the theory of hydrocarbon generation and accumulation,buried hills including Qianmiqiao,Gangxi,Kongxi,andWumaying were analyzed on tectonic evolution,trap types,reservoir character,source rock evolution and time-space relation. There were twotypes of hydrocarbon accumulation:young source in old reservoirs and old source in old reservoirs. Based on development position,structurestyle,reservoir ways and reservoir-forming,five accumulation patterns are: ①old reservoir from new source at reverse throst blocks,②oldreservoir from old source at reverse thrust blocks,③old reservoir from old source at deep-buried thrust blocks,④old reservoir from newsource at intrabasinal upper blocks,⑤monadnock reservoir in basin upper margin.
