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。
Although the Bohai Bay Basin as a whole is a region with a high level of oil and gas exploration in China, there are still quite a wide range of exploration areas and areas that are still low in exploration due to constraints of exploration conditions and means and limitations of geological understanding. Deepening geological understanding can effectively accelerate the process of oil and gas exploration in this basin. According to the change of the geostress field during the evolution of the basin, the paper determined the nature of the basin, divided five stress zones, and analyzed the genesis mechanism. Combined with the status of oil and gas exploration in each zone, oil and gas evaluation was made.
