摘要
同生断层也称生长断层、同沉积断层。通过对大港滩海区同生断层研究发现 ,内部同生断层具有分段和连锁生长特征。同生断层分段成核、分段生长 ,然后追踪连锁为一条断层。凹陷内部同生断层分段生长对地层沉积、油气运移、聚集的控制作用也不相同 ,至使同一含油气系统内部同一断层同一层位在不同地段油气运移、富集规律不同。分段研究凹陷内同生断层 ,对指导油田现场勘探开发具重要实际意义。
The concept of syngenetic fault is known as growth fault or synsedimentary fault. Through the studying on the syngenetic fault in offshore area of the Dagang Oilfield, it is found the internal syngenetic faults had segmented growth feature clearly, they grew segmentedly, and connected to one fault finally. The segmented growth feature of the syngenetic fault in the depression had the different control on the stratigrphic sedimentation, hydrocarbon migration and accumulation. Which makes that in the same hydrocarbon?bearing system, also in the samefault and horizon, just in the different location, the hydrocarbon migration and accumulation pattern different. Segmented study on the syngenetic fault in the depression is of important practical meanings to guide the field exploration and production.
