神通正演模拟子系统研发与应用——以二维声波正演模块的应用为例

Development and application of STseis forward modeling subsystem: A case study of 2D acoustic wave equation forward modeling module

地震正演模拟是地震数据采集、处理、解释的分析基础,为其提供理论依据及科学的评估方法。通过地震正演模拟,可以检验采集设计的合理性、处理和解释成果的可靠性以及反演方法和结果的正确性。有限差分法二维波动方程正演模拟计算速度快、精度高、应用广泛。本文介绍了神通地震正演模拟子系统的功能,并以二维声波波动方程正演模块为例进行了应用效果分析。

Seismdataic forward modeling is the basis of seismic data acquisition, processing and interpretation analysis.The rationality of the seismic acquisition and design, the reliability of the processing and interpretation and the validity of the inversion and the results could be verified with the seismic forward modeling. The 2D wave equation forward modeling with finite-difference method is of quick calculation speed, high accuracy and extensive application. The paper introduces the functions of STseis forward modeling subsystem, and the application efficiency is analyzed by a case history of the 2D acoustic wave equation forward modeling module.
