根据野外地质调查、构造物理模拟和地质综合分析,对陆相断陷盆地中断层两盘裂缝发育特征及其石油地质意义进行了研究。断裂带包括断裂破碎带和裂缝发育带,断层两盘的裂缝发育程度存在着明显的差异,断裂主动盘张裂缝密度大于被动盘,有些断裂被动盘裂缝根本就不发育。在陆相断陷盆地中,处于被动盘的反向断层控制的圈闭更容易形成油气藏。
According to the field geological survey, tectonic physical simulation and comprehensive geological analysis, the development characteristics of the faults in the two faults in the continental faulted basin and their petroleum geological significance are studied. The fault zone includes the fracture zone and the zone of fracture development. There is a clear difference in the degree of fracture development between the two plates. The fracture density of the active fracture plate is larger than that of the passive plate, and some of the fracture plates do not develop at all. In continental rift basins, traps that are under reverse fault control of passive disks are more likely to form reservoirs.
