摘要(Abstract)：
在对车古201潜山的三维地震剖面进行解释分析和构造反演的基础上,根据构造模型和相似理论,用砂箱模型模拟了对该区潜山的构造特征及演化过程。结果表明:a.车古201区的主控断层形态具有上部铲式,深部坡坪式的构造特点,正是这样的边界特点造就了本区的潜山构造;b.主控断层坡折带处的逆断层是在伸展作用下由正断层倒转形成的;c.本区的复杂构造变形是正断层上盘变形和柔性基底不均匀伸展的复合作用结果。
Based on the explanation and structural inversion on the 3D seismic profiles which crossing Chegu201 buried hill, a series of sandbox experiments had been finished. The results of experiment show: a. The spade faults and the deep ramp-flat faults in the structure are the specific characters of the main fault of Chegu201, and these specific characters formed the burial hill structure of this area; b. The reverse fault occurring the slope break area of primary fault was formed as a result of inversion of normal fault in extension; c. The complex structure distortion of this area is caused by compound function of hanging wall distortion of normal fault and non-homogeneous extension of flexible basement rock.
