实际生产资料表明，泌阳凹陷内断层封闭形式已发现有油－油、油－水邻接等八种形式，封闭机理有断面封闭、对盘岩层封闭和孔隙流体压力封闭。断层活动对油气运移聚集的影响主要有两个方面：第一，同生正断层在活动期是流体的渗流通道；第二，断层活动改变了两盘地层的邻接状态。根据对凹陷内几个主要油田的断层研究分析，断层的封闭能力和特征主要与断层规模（断距大小）、两盘地层邻接状态、产状、埋藏深度、流体性质和断层活动等因素有关。
The actual production data show that there are eight forms of oil-oil, oil-water contiguity, etc. in the closed fault type in Biyang sag. The sealing mechanism is closed by section, which is closed to the rock formation and closed by pore fluid pressure. The influence of fault activity on migration and accumulation of oil and gas are mainly in two aspects. First, the syngenetic normal fault is a fluid seepage channel during the active phase. Second, the fault activity changes the adjacent state of the two reservoirs. According to the research and analysis of the faults in several major oilfields in the depression, the sealing ability and characteristics of the fault are mainly related to the size of the fault (the size of the fault), the adjacent state of the two reservoirs, the occurrence, burial depth, fluid properties and fault activity.
