摘要
在区域构造、地层等地质特征研究基础上,对渤海湾盆地济阳坳陷的边界断裂样式、发育特征等进行了分析研究,并探讨其对盆地构造、地层发育、沉积体系、油藏分布等方面的影响。研究发现,随着坳陷边界基底断裂演化程度的提高伸展量增大,相应的沉积盆地构造、沉积特征及其所决定的各项油气地质指标也随之优化。对于东部新生代伸展盆地,这可能是一个普遍规律,对盆地先期评价具有一定的指导意义。
This paper studies the regional structure,formations,style and development of border faults in Jiyang Depression of Bohai Gulf Basin,and discusses their impacts on basin structure,formation development,sedimentary system and reservoir distribution.The study shows that the depression had extended as the improving of evolution degree of border base faults,also optimized was the relevant depositional basin structure,sedimentary characteristics and hydrocarbon index.This may be a common rule in eastern Cenozoic expanding basins and is of guiding significance to basin pre-evaluation.
