沉积物理模拟技术进展及发展趋势

Progress and Developing Tendency of Sedimentary Laboratory Experiments Technique

沉积物理模拟是沉积物物理过程的室内模拟。结合当前的研究进展,将沉积物理模拟技术的发展过程划分为4个阶段:以现象观察描述为主的初级阶段、以底形研究为主的迅速发展阶段、以研究砂体形成过程为主的湖盆砂体模拟阶段和以砂体半定量-定量化描述的模拟阶段。在对国内外几个重要的沉积模拟实验室简要介绍的基础上,按冲积扇、三角洲、扇三角洲、河道沉积等不同沉积相类型,总结了近年来开展的沉积物理模拟实验所取得的成果,指出定量化研究将是沉积物理模拟技术未来发展趋势。

Sedimentary laboratory experiments describe physical process of sediment in laboratory. On the basis of current study progresses, the development of sedimentary laboratory experiments technique is divided into four stages： 1） primary stage with observing and describing sedimentary phenomenon; 2） fast developing stage characterized on the research of bottom configuration; 3）sand-bodies simulation stage for the sedimentary process of sand-body; and 4） semiquantitative-quantitative simulation stage focusing on the detailed description of sand-bodies. After the brief introduction of some important international and domestic sedimentary simulation laboratories, a summary is made on the research of sedimentary physical simulation experiments of domestic experts based on different sedimentary facies types, such as alluvial fan, delta and fan delta. Finally, it is pointed out the developing tendency of sedimentary laboratory experiments technique is a quantitative research.
