| 摘 要： | 东营凹陷岩性油气藏主要发育在下部的超压体系之中.在该压力体系中,由于断裂作用、储集物性等因素的影响,形成了不同充满度岩性油气藏.对不同充满度和类型的岩性油气藏成藏体系的比较分析,建立不同充满度的岩性油气藏油气充注模式,即深部超压高充满度油气充注模式、断层沟通中等充满度油气充注模式及低充满度透镜体油气充注模式.

| Abstract: | Lithologic reservoirs are developed in deep over-pressure system in Dongying sag. Due to effect of faulting, reservoirs quality and dynamic of forming-pool in this system, different fullness degree lithologic reservoirs are developed. Three models of entrapment of lithologic reservoirs are built, base on comparing systems of hydrocarbon accumulation of lithologic reservoirs with different fullness degree and type. The three reservoir entrapment models are: (1) reservoirs with high oil fullness degree at deep and with abnormal high-pressure, (2) medium fullness degree reservoirs with fault incision and (3) low fullness degree lens reservoirs. |
