摘　　要：油田开发阶段断层封闭性研究对于剩余油的挖潜具有重要意义。断层两侧不同砂层组岩性配置的差异导致了断层封闭程度的不同,运用断层两侧岩性配置关系研究方法揭示营32断层的封闭性。沿断层走向岩性配置有很大不同,断距从北向南逐渐变小,增加了同一储层在断层两侧相配置的概率,岩性配置变差。营32断层南段封闭性不好,在注水开发过程中,导致油气穿越断层,发生了油气再运移;而断层北段是封闭的,表明同一条断层具有封闭差异性及动态性。Study of fault sealing property was of great significance for tapping the potential of the remaining oil at the stage of oilfield development. Different lithologic allocation of the sand group at two sides of the fault led to the difference of fault sealing degree. The sealing property of the fault Ying 32 was studied by means of lithologic allocation relation at two sides of the faults. Along the strike of the fault, the fault throw gradually became small from north to south, and the probability of the allocation of the same reservoir between the two sides of the fault increased. As a result, the lithologic allocation became bad. Petroleum remigrated across the fault Ying 32 during the process of waterflooding in the south part due to the bad sealing property, while the fault was sealed in the north part. The sealing property of the same fault was diverse and dynamic.
