摘要: 针对常规地震成像方法难以解决大庆探区复杂构造精确成像的问题,从逆时成像技术的基本原理出发,结合数值模拟及实例应用,系统分析了有限差分阶数、吸收边界条件、逆时成像条件、子波相位校正、背景噪声压制、逆时参数优化等关键因素对逆时成像精度的影响,总结出一套改进了核心算法、提高了成像精度的"高精度"逆时成像技术,并应用于大庆探区实际地震资料复杂构造的逆时成像处理中。结果表明,改进的"高精度"逆时成像技术的应用效果较常规克希霍夫叠前深度成像技术和常规相关法逆时成像技术均有显著改善。该研究成果对于逆时成像技术的理论方法研究及实际应用具有参考价值。

Abstract: The conventional seismic migration methods are difficult to solve complex structure accurate imaging of Daqing seismic data. The key factors on reverse-time migration precision were analyzed, such as finite difference method's order, absorbing boundary conditions, reverse-time imaging condition, wavelet phase correction, background noise suppression,reverse-time parameter optimization. A set of high-precision reverse-time migration techniques is improved in key algorithm and imaging results, which is applied to practical seismic data reverse-time migration in Daqing exploration area. The high-precision reverse-time migration technology is better than that of conventional Kirchhoff pre-stack depth imaging technology and conventional correlation reverse-time ima-ging technology. The results are of some reference to the theory,method,and practical application of reverse-time migration technology.

Key words: dynamic provenance, sequence stratigraphy, paleogeomorphic analysis, reservoir prediction, Yanan Sag, Qiongdongnan Basin
