| 摘 要： | 从断裂带内部结构及其封闭、输导性入手,分析了中国含油气盆地断裂带内部结构特征及其对流体的输导、封闭性的影响,认为含油气盆地的断裂上盘诱导裂缝带的裂缝发育,纵向开启相对较好,是输导油气纵向运移的重要通道,有利于上盘上倾方向各种圈闭聚集油气成藏;而断裂的下盘诱导裂缝带的裂缝不发育,横向封闭性相对较好,有利于遮挡油气而聚集成藏。这是反向断层下盘遮挡油气成藏普遍发育,而顺向断裂上盘圈闭泄露油气风险较大的原因。

| Abstract: | According to the inner structure as well as the sealing and transporting capacity of fault belt,it has been concluded that fissures generate well in the upper block of fault belt in petroliferous basin.Well-developed fissures are favorable for petroleum vertical migration and help reservoir form in the upper block.In the lower block of fault belt,fissures do not generate.Horizontal sealing works well and screens petroleum so as to form reservoir.It explains why screened oil pools are widespread in the lower... |
