摘　　要：三维约束层速度反演技术是建立在指数渐进边界形式速度趋势模型之上,结合了井资料、旁道数据,以阻尼因子全局约束计算层速度的方法。能有效识别层速度异常区域,适用于大倾角低幅构造,少井无井区的速度资料处理。在充分利用Windows操作系统的广泛应用及运行稳定的基础上,结合跨平台的c++图形用户界面库Qt,使用c/c++和fortran语言混合编程,完成了三维约束层速度反演处理系统的研发。该处理系统运用于南海琼东南BD地区实际资料表明:方法能较好的解决纵向连续及横向变速的问题,计算得到的剖面分层贴合层位曲线,能更清晰的描绘构造细节,为储层预测提供依据。The constrained inversion for interval velocity is based on exponential asymptotically bounded veloci- ty mode, combined with well data, bypath data and damping factor to compute the global restriction interval veloci- ty. It can identify anomaly interval velocity area and finish the processing of the seismic data in high inclination an- gle and low amplitude structure area. The processing system is developed by utilizing the stable and high efficient features of Windows operating written by mixed programming system, combined with a cross-platform Qt graphical user interface software library, languages including c/c＋＋ and FORTRAN, and designed by the multi-tread and ob- ject-oriented programming, etc. The technologies obtain good application resulis in actual seismic data from South- Sea BD target area, it can resolve the question about vertical continuous and horizontal variation, the horizon in computed profile next to the actual horizon curve, and describe the structure detail clearly. Above all, the process- ing system provides a solution for the development of other seismic data processing software, and contributes to the reservoir prediction.
