东营凹陷是济阳坳陷油气最富集的陆相断陷凹陷,具备形成岩层油藏的良好地质条件。本文从地层油藏的圈闭形成条件、储层及油气充注动力3方面探讨了东营北带东、中、西段地层油藏富集的差异性,立足勘探实践分析了3方面的差异性对地层油藏油气分布的影响,将有力指导东营北带地层超覆油气藏的勘探开发工作。 Dongying sag is the most abundant oil and gas terrigenous faulted depression in the Jiyang Depression, which has the good geological conditions for the formation of rock reservoirs. This paper discusses the differences of reservoir enrichment in the east, middle and west strata of the north belt of Dongying from the formation conditions of stratum reservoirs, the reservoir and the dynamic of hydrocarbon charge. Based on the exploration practice, the differences in three aspects are analyzed The impact on the distribution of oil and gas in the stratigraphic reservoirs will effectively guide the exploration and development work of stratigraphic overlying reservoirs in the north belt of Dongying.
