在伸展和走滑两种活动体制下，渤海湾盆地早第三纪构造样式有五种类型。孔店—沙四期主要发育非旋转地堑、旋转半地堑、滚动半地堑和走滑地堑，沙三—沙二期以滚动半地堑和复式半地堑为主，沙一—东营期主要发育滚动半地堑、复式半地堑和走滑地堑。盆地构造样式的演化遵循着三个序列，即旋转半地堑→滚动半地堑→复式半地堑序列、非旋转地堑→滚动半地堑→复式半地堑序列和非旋转地堑→走滑地堑序列。演化序列本身存在差异并受断裂活动的控制。构造样式的演化具有明显的地区性特点，后两种序列沿郯庐断裂带、沧东—兰聊断裂带和太行山东麓断裂带发生，与三条岩石圈走滑带吻合。第一种序列发生在上述三条走滑带之间，构成两个伸展区。构造样式的演化与烃源岩、油气藏和含油气系统的性质和分布有着密切的关系。
There are five types of tectonic styles of the Early Tertiary in the Bohai Bay Basin under both extensional and strike-slip regimes. Kongdian-Sha4 mainly developed non-rotating graben, rotating half-graben, rolling half-graben and strike-slip graben. Sand III-Sha II was dominated by rolling half-graben and compound half graben, Dongying main development rolling semi-graben, semi-graben and slippery graben. The evolution of the tectonic pattern of the basin follows three sequences: rotary half-graben → rolling half-grazing → complex half graben sequence, non-rotational graben → rolling half-grazing → double graben sequence and non-rotational graben → walking Slippery grazing sequence. The evolutionary sequence itself is different and controlled by the fracture activity. The evolution of tectonic style has obvious regional characteristics. The latter two sequences occur along the Tan-Lu fault zone, the Cangdong-Lanliao fault zone and the eastern foot of Taihang Mountains, consistent with the three lithospheric strike-slip zones. The first sequence occurs between the three strike-slip belts, forming two extension zones. The evolution of tectonic styles is closely related to the nature and distribution of source rocks, reservoirs and petroleum-bearing systems.
