摘要
通过分析已知油藏的成藏规律,探讨了饶阳凹陷构造转换带与新近系油藏的内在联系,认为构造转换带是油气运移的指向,具有纵横向立体输导系统,可形成以构造圈闭为主的多种圈闭类型。圈闭定型期、断层活动期与生油岩排烃期可形成良好配套关系,伸展构造体系中的变换断层具有封闭能为,构造转换带在多方面有利于油气成藏。目前已在饶阳凹陷两大构造转换带之一的留路—大王庄转换带发现新近系富集油藏,八里庄—薛庄转换带是有利勘探方向。
Through analyzing the known reservoir-forming law,the inner connection between the transfer zone and the Neogene reservoirs in Raoyang sag is discussed.It is considered that the transfer zone,with its longitudinal and transverse stereoscopic conducting system,represents the hydrocarbon migration. So many types of traps dominated by structural traps may develop there.The trap shaping phase,the phase of faults action,and the hydrocarbon expulsion phase of source rocks match well with each other.The transfer faults in the extensional structural system have the capacity of sealing,as well as the transfer zone is favorable for hydrocarbon accumulation in many ways.Neogene enrichment reservoirs have been discovered in the Liulu-Dawangzhuang transfer zone which is one of the major transfer zones in Raoyang sag,as well as the Balizhuang-Xuezhuang transfer zone is favorable for exploration.
