起伏地表物理模拟的水面无接触快速采集方法
Keywords: 起伏地表,有限差分,物理模拟,波场重构
Abstract:
？由于实验室条件的限制,针对起伏地表的物理模拟采集直接在固体表面进行,存在实现难度大、采集速度慢、耦合误差大的缺点。为此,本文基于波场重构原理,提出了一种针对起伏地表的水面无接触快速采集方法,通过直接在水面进行观测、采集,然后由水面观测的地震数据重构固体表面的观测地震数据。该方法将数值模拟和物理模拟结合,既保留了物理模拟的真实性,又利用了数值模拟的易操作性,能够克服起伏地表物理模拟采集难度大、采集速度慢的问题,大大提高了起伏地表物理模拟采集的精度和效率。论文实验部分对数值模型和物理模型分别进行固体观测和水面观测,通过对两种采集方法得到的固体观测地震记录进行比较,证明了该方法的优越性。
