渤海湾盆地演化特征与构造样式

应用勘探地震信息，分析研究了渤海湾贫地从中、上元古代、古生代、中生代到新生代，地质发展历史演化特征，并根据临清地震剖面显示，探索该区在演变历史进程中地壳层厚度的民应力环境转化的规律；论述了盆地在３次断陷－坳陷期形成的力学机制；在综合论述的基础上，归纳总结出盆地内有７种类型盖层构造特征的展布样式。文章最后概述了盆地成油成藏条件与规律并强调进一步加强古生界油气藏勘探与研究的重要意义。

Evolution Character and Tectonic Styles of Bohai Bay Basin

Applying the exploration seismic information, the paper analyzes the evolutlon character of Bohai Bay Basin in geologic history from Mesoproterozoic, Upper Proterozoic, Palaeozoicera, Mesozoic to Cenozoic. According to the Linqing seismic section, the authors explore the laws about the change of crustal derm thickness and stress environmental conversion in the course of evolution history in this area. Next, the forming mechanical mechanisms of the three times fault depression-depression periods are studied. On the basis of synthetlcal discusses, the paper summarizes seven development styles of cap rock tectonic characteristic. Finally,the paper describes the reservoir forming condition and laws in brief, and emphasize the importance of strengthening the exploration of Palaeozoic reservoir.
