| 摘 要： | 针对渤海湾南部埕岛地区的油气成藏特征和较高勘探程度的特点，对埕岛复式含油气系统（composite petroleum system)，含油气系统，亚油气系统和子系统进行了四个不同勘探级次的划分，描述，以及各含油气系统之间相互关系的讨论，从油气的生成，运移，聚集，保存和破坏有机联系的四个方面18种要素，对不同级次的系统用多级模型综合评判的数学方法，进行了综合定量评价，并在此基础上优选出下一步的有利勘探目标。

| Abstract: | Chengdao area is located in the southern part of Chengbei lower convex of Bohai Bay basin，China．This area contains stratigraphic sequences of almost all ages from Archaean to Tertiary. The structure style shows the characteristics of dyadic structures，and belongs to a typical burial hill-drape anticline Petroleum exploration in the area demonstrates that Chengdao area itself is weak in hydrocarbon generation and the hydrocarbon in the pool came from surrounding depressions including Chengbei depression，Shanan depression，Bozhong depression an d Zhuangdong depression．The hydrocarbon accumulation system in the area is complex，with more than one source rocks，and multiple stages of migration and accumulation．Based on various fundamental geological factors and processes that dominate the hydrocarbon formation and accumulation，the Chengdao composite petroleum system is identified．Four hierarchy levels of the composite petroleum system is subdivided and described，which include 1 composite petroleum system,3 petroleum systems,12 sub-systems and 48(12×4)4th order systems. |
