| 摘 要： | 中生代左行走滑和早第三纪伸展作用共同控制了渤海海域早第三纪的构造格局，按凹陷和凸起的走向将研究区划分为西部坳陷，西部隆起，郯庐西坳陷和郯庐东坳陷，郯庐西坳陷油气生成量和油气资源量在渤海海域油气总生成量和总资源量中所占比例远高于其它3个单元，沙河街组三段是主力烃源层，生油高峰在东营期末，早第三纪末期和晚第三纪一第四纪是两个油气运移期，油气主要分布在富生烃凹陷西侧的隆起上，郯庐断裂对渤中凹陷油气运移的主方向起着重要控制作用，渤海海域油气运移主方向的研究对当前的油气勘探具有重要意义。

| Abstract: | The Paleogene tectonic framework in Bohai Bay was controlled by both Mesozoic sinistral strike slip and Paleogene extension resulted from diapiric intrusion of mantle. The basin is divided into four units according to the strikes of sags and uplifts. Those sags along the detachment faults are prolific oil-gas depressions. The third member of Shahejie formation was the main source rock. The direction of oil and gas migration was in the west towards uplifts near the sag. The movement of Tan-Lu fault controlled the hydrocarbon migration in Bozhong sag. The paper points out that search into main migration path of oil and gas is very important in current petroleum exploration in this Basin. |
