摘要/Abstract

摘要： 地震波振幅属性是识别目的层岩性的重要参数，但该属性受上覆界面的影响较大。为了弄清上覆水平界面对目的层地震波振幅的影响，从正演模型出发，利用双程波动方程进行模拟，研究地震波在不同速度、不同尺度的上覆地层中传播时振幅的变化，建立上覆界面与目的层地震波振幅之间的联系，通过构建包含完美匹配层（PML）边界衰减系数的高阶交错网格有限差分公式，使用GPU进行并行计算加速，最终获得三维层状水平速度模型目的层地震波振幅的变化规律。结果表明，当上覆水平界面的反射系数发生变化时，目的层地震波成像振幅的变化范围及变化趋势都会随之发生相应的改变，尤其当上覆水平界面的反射系数趋于一致时，目的层地震波成像振幅便会发生异常性的变化。该研究成果可为地震资料处理解释过程中正确识别目的层岩性提供一定的理论帮助。

Abstract: Seismic amplitude is an important parameter to identify the lithology of target zone, however, it is greatly affected by overlying stratum. Based on the forward modeling, the numerical simulation of two-way wave equation was applied to study the amplitude change of seismic wave when it travels through the overlying stratum with different velocity and scale, and the relationship between the overlying stratum structure and seismic amplitude of the target zone was discussed. By building high ordered staggered-grid finite difference algorithm containing PML (perfect matching layer)attenuation coefficient and using GPU parallel acceleration, the amplitude change regularity of the target zone of 3D layered velocity model was defined. The experiment results show that the amplitude of the target zone will change accordingly with the change of reflection coefficient of the overlying stratum, and it will change abnormally especially when the reflection coefficient of overlying stratum tends to be consistent. This study results are favorable for correct lithology identification by seismic data.
