郯庐断裂带控制了渤海东部凹陷、凸起的形成、演化,也控制了烃源岩、储盖层及圈闭的展布,进而影响了渤海东部地区油气的性质。郯庐断裂带在渤东地区的强烈构造作用,使得该地区油气勘探变得很复杂,同时也使得油气性质变得更加难以进行分类。因此,准确分析该地区的构造作用方式,特别是渤海新构造的晚期运动方式,以及断裂带对该地区地层油气的影响方式,有助于准确分析郯庐断裂带对渤海湾地区油气成藏的影响,有助于今后的油气勘探。

The Tancheng-lujiang fractuer zone controlled the formation and evolution of sags and swells in the eastern Bohai Sea , but also controlled the distribution of source rocks , reservoir seal assemblages and types in the basin , and then effects the petroleum characteristics in the eastern Bohai Sea. Because of its intense tectonism of Tancheng-lujiang fracture zone in the eastern Bohai Sea , that cause petroleum provement turning to more complexity , and contemporary cause the complexity of petroleum characteristics and difficult to classify tectonism methods of these area. especially for the late movement method and its effections to petroleum in stratas of fracture zone , which can help to analysis the etfections to petroleum accumulation in Bohai Sag , and help to hydrocarbon exploration in the future.
