早白垩世至早第三纪期间，渤海湾地区在区域帚状构造应力场作用下，形成了巨型冀鲁帚状构造体系，其不同级序的构造成分均具有帚状构造体系特征，帚状构造的生成和发展不仅控制了该区的构造格局，而且控制了沉积发育、油气生成和分布．其中，一级构造控制巨型复式油气聚集带的形成和分布；二级构造控制生油凹陷的生油条件和油气富集程度；三、四级构造控制各种复合油气藏的形成与分布；五级构造是油气聚集的主要场所。进一步揭示了不同级序的构造与沉积、油气藏形成和分布的关系，对今后石油勘探开发及在成熟探区寻找隐蔽油藏有重要意义。
From the Early Cretaceous to the Early Tertiary, the Bohai Bay region formed a giant Jilu broom-like structural system under the action of the regional broom-like tectonic stress field. The structural components in different orders all have the characteristics of a broom-like tectonic system. The formation and development of tectonics control not only the structural pattern of the area but also the sedimentary development, hydrocarbon generation and distribution. Among them, the first-level structure controls the formation and distribution of the giant multi-type hydrocarbon accumulation zone; the second-level structure controls the oil generation conditions and oil-gas enrichment degree of the oil-producing depression; the third and fourth-level structures control the formation and distribution of various composite reservoirs; Level structure is the main site for hydrocarbon accumulation. Further revealing the relationship between the structure and deposition of different orders, the formation and distribution of oil and gas reservoirs, and is of great significance for the future exploration and development of oil and the search for hidden reservoirs in mature exploration areas.
