vsp逆时偏移及其存储策略研究
Keywords: vsp,逆时偏移,随机边界,pml边界
Abstract:
？在逆时偏移算法中,应用常规的随机边界方法虽可节约存储空间,但浅层常伴有随机噪声。应用pml边界方法虽可改善上述状况,却又面临地震波场存储的压力。为此,本文采用优化系数的高阶有限差分方法实现vsp数据逆时深度偏移,采用拉普拉斯去噪方法压制低频噪声,并兼顾考虑精度和存储,在pml边界震源波场正传过程中保存部分波场,进而利用保存的信息与检波点波场同步反传,不仅可有效地节约存储空间,也确保了替代波场信息的可靠性。断层模型测试表明,本文方法能够以低存储实现高精度的vsp逆时偏移,相比于地面地震偏移,断层成像更清晰、准确。
