摘要: 位于渤海湾第三纪裂陷区的黄骅坳陷是一个复杂的叠置型裂谷盆地.前裂谷期中生代盆地构造格架制约了黄骅坳陷第三纪裂陷运动的发展,并对盆内潜山形成分布产生重要的影响.据地震资料分析,黄骅坳陷区中生代经历了印支及燕山两大造山构造幕,形成了叠加在印支期NWW向宽缓复式褶皱背景上的近南北向走滑构造系统.这些走滑挤压构造系统,构成了黄骅坳陷“残留型”及“叠置型”潜山的基本构造格架,并对新生代断块山的形成起到了重要的影响.而中生代构造热演化事件则控制了黄骅坳陷区潜山圈闭特点、储集条件、油气类型及形成油气田的规模,是潜山勘探选区重要的评价依据.

Abstract: Huanghua Depression is a structurally complicated rift basin formed during Tertiary in Bohai Bay Region.Its pre-rift structural system,mainly generated during Mesozoic era,dramatically affected the rifting tectonics and the structural styles of buried-hills in Huanghua Depression.A ccording to seismic interpretations and tectonic analysis,Mesozoic tectonic deformation can be clarified into Indosinian and Yanshanian episodes.A complexes N-S trending strike-slipping fault and fold system in Huanghua Basin which developed during Jurassic-Cretaceous overprinted Indosinian anticlinorium and syclinorium.It formed the basic structural sketch of "relics" and "hybrid" buried-hill and made a great influence on the evolution of Tertiary faulted-block hills.Thus,Mesozoic tectonic events in Huanghua Depression can be treated as an most important factor for evaluating hydrocarbon bearing potential in buried-hills,due to their domination in buried-hill traps,reservoirs,oil types,and the scale of oil pools in Huanghua Depression.

Key words: Huanghua Depression, buried-hill, Mesozoic, tectonic, hydrocarbon accumulation
