摘　　要：渤海湾盆地虽整体上是我国油气勘探程度较高的地区 ,但仍有相当广阔的地区和领域勘探程度还很低 ,其原因有勘探条件和手段的制约 ,也有地质认识的局限。深化地质认识可有效地加快该盆地的油气勘探进程。本文根据盆地演化过程中的地应力场变化 ,分析、确定了盆地性质 ,划分出了 5个应力区带 ,并分析了成因机制 ,结合各区带的油气勘探现状 ,进行了油气评价。Bohai Bay basin is a region which oil/gas exploration level is higher in China,but uneven in exploration is still existence in the region,and a large amount of area has lower level of exploration.Some of them are constrained by conditions and tools and others are limited by geological knowledge.Deepening the geological knowledge of the basin can accelerate effectively the process of oil/gas exploration in that basin.According to the change of crustal stress field during development of the basin,the paper analyzed and determined the property of the basin,divided 5 stress zones,analyzed mechanism of contributing factors and put forward appreciation of oil/gas for each stress zone combining with current condition of their oil/gas exploration.
