| 摘 要： | 走滑断裂在渤海海域广泛分布，深刻影响着沉积盆地的形成与演化，同时也深刻影响着源－汇体系的形成和演化.在对渤海海域大量钻井资料和地震资料分析的基础上，认为走滑断裂对渤海古近系源－汇体系的控制作用主要表现在:走滑断裂压扭作用控制了局部物源体系的形成；走滑断裂的张扭作用控制了沟谷低地的形成；走滑断裂的水平运动控制源－汇体系的横向迁移.走滑断裂带源－汇体系发育模式十分复杂，渤海古近系常见的主要有S型走滑断裂带源－汇体系模式、叠覆型走滑断裂带源－汇体系模式、帚状走滑断裂带源－汇体系模式、共轭走滑带源－汇体系模式.开展走滑断裂带源－汇体系特征及其控砂模式的探讨，对含油气盆地的储层预测具有重要的意义.

Control of the Strike-Slip Fault to the Source-to-Sink System of the Paleogene in Bohai Sea Area |

| Abstract: | The strike slip faults are widely distributed in Bohai sea area and they play an important role in the formation and evolution of the sedimentary basin and the Source-to-Sink system. According to the principles of Source-to-Sink system analysis, this paper focuses on the study of control of the strike slip fault over the Source-to-Sink system of the Paleogene in Bohai on the basis of a large number of drilling data and seismic data analysis. It is found that the transpression of the strike slip faults controls the formation of local provenance system. and the transtension of the strike slip faults controls the formation of eroded ravines and valleys. The horizontal movement of the strike-slip fault controls the lateral migration of Source-to-Sink system. The Source-to-Sink system in the strike slip fault zone is more complex than that of the simple extension fault zone. There are four kinds of common Source-to-Sink system of strike slip faults in Paleogene in Bohai including S type strike slip fault source sink system mode, en echelon type strike slip fault source sink system mode, brush strike slip fault source sink system mode, and conjugate strike slip fault source sink system mode. The study on the characteristics of Source-to-Sink system and its sand control pattern of strike slip fault zone is very important for reservoir prediction in petroliferous basin. |
