松辽盆地敖古拉-他拉哈断裂带成藏机制
|
摘要
敖古拉-他拉哈断裂带油气藏类型多样,成藏机制复杂,断裂在成藏过程中起着重要作用。通过对敖古拉-他拉哈断裂带的断层进行分期研究,探讨了各期断层对该地区中浅层油气成藏的控制作用,认为该地区中浅层的油气成藏过程中有两期断层对油气成藏起到至关重要的作用:一是青一段末形成在姚家组末又重新活动的断层,二是明水组沉积末形成的断层。这两期断层在扶余、高台子油层油气成藏过程中,断裂在横向上实现青一段油源岩与储层的侧列配置,为油气的侧向运移创造条件,在有利的断层侧向封堵或岩性圈闭中聚集成藏,形成上倾方向被断层遮挡的断层油藏、断层-岩性油藏,断层主要是通道和遮挡成藏作用。在黑萨葡油层油气成藏过程中,这两期断层主要发挥油气运输通道作用,遮挡成藏作用较弱,油气藏类型以岩性油藏为主,断层油藏较少。
The reservoir-related Aogula-Talaha fault zone is characterized by various types of oilgas reservoir,complex reservoir-forming mechanism,and obvious control on the process of reservoir formation.Based on the study of the active periods of the Aogula-Tahala fault zone,the faultcontrol of oil and gas accumulation of the middle and shallow oil and gas pools is analyzed.It shows that two types of faults play a crucial role in controlling the oil and gas accumulation of the middle and shallow formations.One type is the faults formed at the end of K_2qn_1 formation and reactivated again at the end of K_2y formation,the other is the faults formed at the end of K_2m formation.In the process of oil and gas accumulation in the Fuyu and Gaotaizi reservoirs,the faults enable the source rocks of K_2qn_1 to contact directly to the reservoirs horizontally,and created conditions for lateral migration of hydrocarbon.Then the fault reservoirs and fault-lithologic reservoirs developed because of the laterally sealing of the faults and compacted rocks.At this time,the faults acted as the channels or blocks for oil and gas migration.However,in the process of oil and gas accumulation in the Heidimiao,Saertu and Putaohua reservoirs,the faults mainly act as the channels for oil and gas migration.So the reservoirs are mainly lithological reservoirs with minor fault controlled reservoirs.
