摘要: 层序地层学研究已在陆相湖盆中取得良好的应用效果,在陆相湖盆的地层对比、沉积体系空间分布预测中发挥重要作用。坳陷湖盆在基底受压变形过程中,常在盆缘形成地形坡折带,以坡折为界,基底的沉降速率和原始地形坡度等控制层序发育的重要因素在其两侧均存在显著的差异,这在很大程度上控制了层序的发育模式和沉积体系的空间配置关系。通过对基底沉降速率、湖平面变化速率、沉积物充填速率、沉积物充填准则、岩相确定原则等数学模 型的建立,模拟了具有地形坡折带的坳陷湖盆的层序发育和相演化过程。实际资料与模拟结果的对比分析表明,模拟具有很好的效果。Abstract: Sequence stratigraphic research in lake basin has got good application, which takes a significant role in stratigraphic correlation and sedimentary system distributing prediction in lake basin. Topographic ramp often come into being in the edge of depression lake basin in the process of basin basement deformation under extrusion stress, the key factors controlling sequence development such as subsiding rate of basement and initial topographic slope have apparent difference on the two sides of ramp, which in turn has controlled the sequence development model and the space allocating relation of sedimentary system to great extent. By constructing mathematics model of basement subsiding rate, changing rate of lake water surface, sediments filling rate, sediments filling rule, and facies defining rule, computer simulation were put forward to recur the sequence developing and facies changing procedures in lake basin with topographic ramp. Comparison between actual data with simulating shows that the simulation result is available.
