中文摘要：

结合实钻井地质资料，对渤海湾盆地内各次级构造单元的地震剖面资料进行统层对比与深度校正，获得了渤海湾盆地新生界各主要组段地层残留厚度分布网，从整体卜反映了全盆地新生界沉积格局与残留地层分布特征。通过深入揭示残留地层所蕴涵的构造信息，为正确认识渤海湾盆地新生代形成演化机制提供了新的依据。对不同时期残留地层分布面积、沉积中心、沉积长轴的综合分析和对比表明，渤海湾盆地自孔店期至东营期总体上是受西太平洋板块俯冲作用所产生的弧后拉张应力控制，且在其形成演化的整个过程中还持续叠加有右旋剪切应力的影响和作用，并认为这种右旋剪切应力场可能是南郯庐断裂右旋走滑活动和印藏碰撞远距离效应所共同产生的。

英文摘要：

Remnant thickness distribution maps of all main Cenozoic formations and members of Bohai Bay Basin were obtained by conducting division, comparison and depth validation of seismic profile data for all secondary tectonic units of Bohai Bay Basin, as well as by using geological data of real drilling. These maps clearly reflect the complete sedimentary framework of the basin and the distribution characteristics of the Cenozoic remnant formations. Through deep revealment of the geological information, new evidence was obtained for a correct recognition of the Cenozoic forming and evolution mechanism of Bohai Bay Basin. The results of cmnprehensive analysis and comparison of spacial distribution, sedimentary center and long axis strike of remnant formations of different sequences indicate that the whole basin was under the control of back-arc extensional stress produced by the subduction of the West Pacific Plate beneath the Eurasia Plate from the Kongdian to the Dongying sedimentary periods. However, the influence and interaction of dextral shear stress superimposed continuously in the entire process of Cenozoic forming and evolution of this basin. This stress field is supposed to be related to the combination of the dextral slip activity of Tanlu fault with the far-distance effect of the India-Eurasia collision.
