济阳坳陷构造活动频繁、岩相复杂,地层油气藏多处于盆缘,决定了油气输导方式多样。基于对济阳坳陷已探明的古近系—新近系地层油气藏油气输导过程的剖析,将古近系—新近系地层油气藏油气输导方式划分为3类4种,即断层—骨架砂体型、断层—骨架砂体—不整合型、断层—不整合型。其中,断层—骨架砂体型可进一步细分为断层—不整合面之上骨架砂体型和断层—不整合面之下骨架砂体型2种。不同的输导方式分别控制着相应的油气藏类型。在总结各种油气输导方式的基础上,建立了古近系—新近系地层油气藏油气输导综合模式。
The Jiyang Depression is characterized by frequent tectonic activities and complex lithofacies, and the stratigraphic reservoirs are mostly located at the basin margin, which determines the diversified modes of oil and gas transportation. Based on the analysis of the proven oil and gas transport processes in the Paleogene-Neogene stratigraphic reservoir in the Jiyang Depression, the oil and gas transmission modes of the Paleogene-Neogene stratigraphic reservoirs are divided into three types and four types, that is, the fault- Skeleton sand body type, fault - skeleton sand body - unconformity, fault - unconformity. Among them, the fault-skeleton sandbody type can be further subdivided into 2 types of skeleton sand bodies below the fault-unconformity and below the fault-unconformity. Different modes of transport control the types of reservoirs respectively. On the basis of summarizing the various modes of oil and gas transport, a comprehensive oil and gas transport integrated model for Paleogene-Neogene stratigraphic reservoirs was established.
