【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。
[Abstract]:The Aogula-Talaha fault zone has various types of oil and gas reservoirs and complex reservoir forming mechanism, and the fault plays an important role in the process of reservoir formation. Based on the stage study of the fault in the Aogula-Taalaha fault zone, the controlling effect of the faults on the formation of oil and gas reservoirs in the middle and shallow layers of the area is discussed. It is considered that there are two phases of faults in the process of oil and gas accumulation in this area: one is the fault formed at the end of Qingyi formation and the other is the fault formed at the end of deposit of Mingshui formation. In the process of oil and gas reservoir formation in Fuyu and Gaotaizi reservoirs, the faults laterally realize the lateral configuration of source rocks and reservoirs in Qingyi formation, thus creating conditions for lateral migration of oil and gas. In favorable fault lateral sealing or lithologic trap accumulation to form reservoir, the updip direction is blocked by fault reservoir, fault-lithologic reservoir, fault is mainly channel and block reservoir formation. In the process of oil and gas accumulation in Hesa oil and gas reservoir, these two faults mainly play the role of oil and gas transportation channel, but the effect of blocking reservoir formation is weak, the type of oil and gas reservoir is mainly lithologic reservoir, and the fault reservoir is less.
