摘　　要：在对济阳坳陷断陷稳定期至坳陷初始期盆地结构、构造、沉积环境、充填方式及岩浆活动等特征分析的基础上,界定断陷稳定期至坳陷初始期的过渡阶段为断拗转换期。详细阐述了济阳坳陷断拗转换期的基本特征。对断拗转换期的成藏条件进行了分析,分析表明优质的储集岩、大型断裂、不整合面及圈闭与优质烃源岩的有机配置为油气成藏提供了有利条件,为下一步油藏勘探提供了理论依据。This paper analyzes the basin structure,deposition environment,filling style and magmatic activity in Jiyang depression from stable faulting stage to initial subsiding stage,and defines the stage from stable faulting to initial subsiding as fault-sag transition stage.The basic features of the transition stage are elaborated in detail.Oil accumulation conditions during the transition stage are analyzed,indicating that favorable conditions of reservoir rock,large faults,unconformity,and good configuration of trap and source rock contributed to hydrocarbon accumulation.
