渤海是渤海湾盆地的重要组成部分，是济阳、黄骅、辽河三大坳陷向海域的延伸与交汇，海域各凹陷的发育演化与防 区基本一致。凹陷的变迁主要受控于地幔的洪升及周边三座大山格局。控凹断裂是伸展断裂，而不是走滑断裂，郯庐断裂 对凹陷的沉积控制作用不明显。渤中凹陷有别盆地诸凹陷，沉积巨厚的东营组，并显示了良好的富生烃前景。海域有四大 富生烃凹陷（辽中、渤中、岐口、黄河口）。有五大勘探领域（凸起浅层及倾没端、浅层构造、古潜山及前第三系、断裂构造带、 凹陷的斜坡带）。海域潜在的资源量可与陆区三大坳陷媲美，寻找油气前景广阔，是我国东部陆区的接替战场。
The Bohai Sea is an important part of the Bohai Bay Basin. It is an extension and intersection of the three major depressions in Jiyang, Huanghua and Liaohe rivers. The development and evolution of each depression in the sea area is basically consistent with that of the zone. The change of the sag is mainly controlled by the rising of the mantle and the pattern of the three mountains around. Controlled-notch faults are extensional faults rather than strike-slip faults, and the depositional control of the Tancheng-Lujiang fault depression is not obvious. The Bozhong Sag has dimples in other basins and thick sedimentary Dongying Formation and shows a good foreground of enrichment. There are four sea-rich hydrocarbon-producing depression (Liaozhong, Bozhong, Qikou, the Yellow River estuary). There are five major exploration areas (shallow bursting and dumping, shallow structure, buried hill and the former Tertiary, fault zone, depression slope zone). Potential resources in the sea area can be compared with the three major depressions in the Lu region. Looking for a promising oil and gas field, it is the succession battlefield of the eastern continental land.
