| 摘 要： | 在地表复杂的工区进行三维地震勘探，静交正是资料处理中的一个重要环节。本文提出了用折射波初至时间计算静校正量的新方法，即分别在共炮点域，共接收点域，共偏移距域交互计算静校正量。

| Abstract: | Static correction is an important step in processing 3 D seismic data from surface complicated area. A new method for deriving static correction values from first breaks of refraction wave is advanced here, by which the static corrections are estimated interactively in common shot, common receiver and common offset domains respectively. Global optimum solution may be obtained by making interactive iteration and statistical analysis of a great deal of data. Real processing results indicate that the method can be used to solve the problem of static correction in complicated area. |
