卫城构造卫古2井区断层封闭性评价

卫城构造位于东濮蚴陷中央隆起带北部，背斜大多被断层切割，油气藏的形成和破坏与断层关系密切。利用断层封闭研究方法对卫城构造断层封闭性进行评价，认为不同地层由于受后期成岩作用影响，同一条断层在不同深度段的封闭性可能截然不同，断层封闭与油气藏的形成在时间上须匹配一致。

Seal Ability of Faults to Hydrocarbon in Weigu-2 Well Area of Weicheng Tectonics

Weicheng tectonics being located in the north corner of Dongpu depression central uplift belt, the anticlines are usually be cut by the faults, the formation and breakage of the oil and gas pool are sharply relationship with the faults. By means of the theoretic model of fault seal, to evaluate Weicheng tectonics. It is discovered that the seal of the fault may be sharply different in different depth in same area, and the formative time of the pool must match consistently with the seal of the fault.
