摘　　要：页岩中虽然广泛存在有机质,只有在生、运、储合适的条件下,才能生成页岩油藏,在页岩中寻找油气富集的圈闭,是页岩油勘探取得突破的关键。通过对胜利油田页岩油基本特征的分析,结合断裂发育对页岩中成烃、成储、赋存等的探讨,认为断裂发育对页岩油富集具有显著作用。东营坳陷页岩的热演化程度因断裂发育而发生变化,导致其储集空间呈现出无机孔隙,以粘土矿物为骨架成分的纹层泥页岩是最有利的储集体之一,晶间孔、粘土片间孔、粒间孔、溶蚀孔和裂缝等无机孔隙为油气向井底流动提供了通道,是探井获得高产油气流的一个重要机理。Although organic matter is widely present in shale,shale oil reservoirs can only be generated under suitable conditions for generation,transportation,and storage.Finding oil and gas enriched traps in shale is a key task in shale oil exploration.Through the analysis of the basic characteristics of shale oil in Shengli Oilfield,combined with the exploration of fault development on hydrocarbon generation,storage,and occurrence in shale,it is believed that fault development has a significant effect on shale oil enrichment.The degree of thermal evolution of shale in Dongying Depression changes due to the development of faults,resulting in inorganic pores in its reservoir space.Laminated shale composed of clay minerals as the skeleton is one of the most favorable reservoirs.Inorganic pores such as intergranular pores,clay interlayer pores,intergranular pores,dissolution pores,and fractures provide channels for oil and gas to flow towards the bottom of the well,which is an important mechanism for exploration wells to obtain high yield oil and gas flow.
