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.
The strike-slip faults are widely distributed in the Bohai Sea, and have a profound impact on the formation and evolution of sedimentary basins. They also profoundly affect the formation and evolution of source-sink systems. Based on a large amount of drilling data and seismic data in the Bohai Sea, The slippery fractures control the Paleogene source-sink system in the Bohai Sea mainly in the following aspects: the formation of local source system is controlled by the compression-torsion of the strike-slip faults; the torsional deformation of the strike-slip faults controls the formation of lowland in the valley; The horizontal movement of the source of control - the Department of the Department of the horizontal migration of the strike-slip fault source - the Department of the Department of the development model is very complex, the Bohai Paleogene are common S-type strike-slip fault source - sink system mode, Fault source-sink system model, broom-shaped strike-slip fault source-sink system model, conjugate strike-slip source-sink system model.On the basis of studying the characteristics of source-sink system and its sand control mode in strike-slip fault zone, Reservoir prediction in petroliferous basins is of great significance.
