摘要
本文介绍了声学波动方程的基本理论,并使用高阶交错网格有限差分算法对塔里木盆地库车坳陷逆掩推覆构造进行数值模拟。通过声学波动方程对逆掩推覆构造模型进行正演和逆时偏移,表明高阶交错网格有限差分法具有高效、精确、实用的特点,具有广阔的应用前景和实际意义。
This paper introduces the basic theory of the acoustic wave equation,and uses high-order staggered-grid finite-difference algorithm to simulate overthrust nappe structure in Kuche depression of Tarim Basin.Through forward modeling and reverse time migration,it indicates that high order staggered grid finite difference method is effective,accurate and practical which has broad application prospects and practical significance.
