摘要
区域构造应力场、营潍断裂右旋走滑扭动、重力差异压实、热沉降以及地幔拆沉引起的均衡调整作用共同控制和影响了渤海浅层上第三系和第四系的构造变形和沉降沉积中心的形成.渤海新生代叠加复合的盆地性质和强烈的新构造运动与周边板块活动的动力学背景密切相关.浅层圈闭在渤海油气勘探中占据重要地位,晚期断层对渤海浅层大油气田的分布起控制作用,不同类型浅层背斜圈闭对油气富集程度也有重要影响,据此归纳出两种基本油气运聚模式.
The shallow tectonic deformation and the development of subsidence-deposition center during Neogene and Quaternary are controlled by regional tectonic stress field, dextral strike slip of Ying-Wei Fault, gravitational differential compaction, thermodynamic subsidence and isostatic equilibrium due to mantle detachment-sagging in Bohai Bay Basin. The Basin' Cenozoic overlapping-combination and strong neotectonism are closely related to geodynamic setting of adjacent plate movement. It is very important to investigate tectonic derformation in oil and gas exploration, because the distribution of major oil and gas fields is clearly controlled by late faults, and different types of shallow anticlinal traps may have a significant effect on degree of hydrocarbon enrichment. Based on this knowledge, two primary models of hydrocarbon migration and accumulation can be concluded.
