中文摘要: 早期认为准噶尔盆地西北缘扎伊尔山构造带是典型的逆冲推覆构造体,但其在新的过山二维地震剖面上表现出冲断-走滑构造的特征,"石炭系—二叠系挤压推覆"和"三叠系—侏罗系压扭走滑"两阶段形成了前陆冲断带完整的冲断-走滑体系。通过物理模拟西北缘挤压、扭动两个阶段地层、断层性质和样式变化,证实了西北缘冲断-走滑构造体系的存在,总结其发育规律,归纳出平面"川"字型样式和剖面"从"字型模式。地质构造模式的建立为西北缘整体构造认识指出新的方向,同时对地震解释和井位部署具有重要作用。
Abstract:As the exploration direction transfers to orogenic belt in the northwestern margin of Junggar Basin, the thrust belt of Zaire Mountain has become the exploration focus. Previously, the thrust belt is thought to be typical over-thrust and nappe belt, but the fault space composition relationships on the seismic sections show thrust\strike-slip-fault belt characteristics. The whole system of thrust\strike-slip-fault belt can be divided into two stages. The first stage is thrust-nappe during Carboniferous to Permian, and the second stage is thrust-torsion strike-slip during Triassic to Jurassic. In the physical simulation experiment, the characteristics and style changes of strata and fault in the two stages above are simulated, and it is confirmed that the thrust\strike-slip system really exists. Summarizing the development rules, we induce "chuan" word style on the plane and "from" word model in profile. The establishment of geological model provides a new direction for understanding the whole northwestern margin structure system. At the same time, it plays an important role in seismic interpretation and well location selection, and it also provides guidance for further exploration.
