摘要： 在定量分析济阳坳陷馆陶组断层活动强度和总结断层活动规律的前提下,系统研究了该时期断层活动对油气成藏的控制。研究结果表明,馆陶组沉积期继承性活动的主干断层和馆陶组内部活动的次级小断层是油气纵向运移的主要通道;断层活动通过对油气纵向运移的控制来控制油气的垂向和平面分布,主干断层和次级断层的活动时期以及活动强度决定了馆陶组沉积期油气藏的垂向分布和平面分布的差异。并预测济阳坳陷下一步油气勘探的主战场应在沾化凹陷和滩海地区。

Abstract: This paper presents the quantitative analysis of fault activity intensity and regularity of Guantao formation and the systematic study of its effect on controlling the hydrocarbon accumulation. The results show that the inherited major fault and the sub-fault of Guantao formation served as the main channels for vertical hydrocarbon migration; the fault activity controlled the vertical and horizontal distribution through its control to vertical hydrocarbon migration; the active stage and intensity of the major fault and the sub-fault determined the difference between the vertical and the horizontal distributions of oil-gas reservoirs in Guantao stage. It is predicted that the main areas for petroleum prospecting in Jiyang depression could be at Zhanhua sag and beach area.

Key words: Jiyang depression, Guanta formation, fault activity, hydrocarbon accumulation, control effect
