滨海断裂系位于歧口凹陷北部,由北东向的滨海断层、大张坨断层、港东断层、唐家河断层和东西向的歧中断层组成,生烃凹陷、储集体与有利构造部位配置关系、长期活动的断层及不整合面、圈闭形成期与油气运聚期配置关系等因素控制了本区油气富集富集程度和展布规律,明确成藏主控因素对本区不同构造部位的勘探方向具有重要意义。 The Binhai fault system is located in the northern part of the Qikou sag and is composed of the northeastern marina, the Dachangtuo fault, the Hong Kong-East fault, the Tangjiahe fault and the east-west divergence fault. The hydrocarbon-generating sags and reservoirs are well-proportioned with favorable structural parts. The faults and unconformities in the long-term activities, the relationship between trap formation period and the configuration of hydrocarbon migration and accumulation control the degree and distribution of oil and gas enrichment and enrichment in this area, and make clear that the main controlling factors for the exploration of different tectonic parts in this area The direction is of great significance.
