| 摘 要： | 对沉积埋藏史、构造演化史、应力场演化史进行了研究，提出了通过计算地史时期断面所承受的正应力来研究断层封闭演化史的方法。运用该方法对崔庄地区崔６、崔７两条主要断层进行了分析。结果表明，埋藏深度不同，断面正应力的大小也不同。吴堡运动时期，两条断层为开启状态；三垛运动时期，两条断层均承受压应力，但崔６断层的封闭性优于崔７断层，即成藏期封闭性好的断层控制的断块，其油气富集程度高；反之，油气富集程度就低。

| Abstract: | The deposition evolution, tectonic evolution and stress field evolution are analyzed. A method for studing on the evolution of fault sealing properties by using the calculation of the normal stress on the fault surface in history are proposed. This method is applied to analyze Cui 6 and Cui 7 faults in Cuizhuang. The stresses on the fault surface are various at different depths. Two faults were open in the period of Wubao movement, and two faults were sealing in the period of Sanduo movement. The sealing property of Cui 6 fault is better than that of Cui 7 fault. The method can be used to determine the distribution of oil and gas. |
