平面可视化技术对山东德南断裂系的精细识别

德南断裂带是山东德南洼陷的主要油气聚集场所 ,精细识别各断层的分布有重要的现实意义。将平面可视化技术应用于德南断裂的精细识别取得了很好的效果 ,已识别出德南断裂是一个向西散开的断裂系 ,它从北到南由 1、 2、 3号北倾断层组成 ;1、 2号断层最终汇聚为一条 ,2号断层下降盘发育 3～ 4条反向补偿断层 ;3号断层是一个小型的断裂系 ,由 5～ 7个北倾断层组成 ,平面上亦向西散开 ;剖面上该断裂系主要反映为向上分开、向下汇聚的帚状断裂系 ;同时还发现了由 3号断裂系控制的断块群。对德南断裂系的精细识别为进一步的钻井勘探和储层建模的研究提供了可靠的依据

Application of plane visualization to Denan fracture system,Shandong Province

It is important to recognize the distribution of the faults in Denan fault belt,where there is high potential in oil and gas. The plane visualization is a tool to visualize the 3-D features data which are unseen by an interpreter. By using this technique to the Denan depression it is found out that Denan fault is a fracture system which fans out westward and is composed by faults No.1, No.2 and No.3 from north to south. The fault No.2 merging with the fault No.3 eastward forms a feather fracture system combining with the 3-4 compensation fault on its footwall. The faults No.3 is also a small-sized fracture system composed of 5-7 faults with the same obliquity. All those features are dominantly broom-like on the profiles. And a lot of fault blocks controlled by the fault No.3 are founded. These studies will provide a reliable support for the drillings and reservoir modeling in the future.
