摘　　要：在地表复杂地区，静校正是地震资料处理中的一个重要工作。本文提出一个用折射波初至时间计算静校正量的新方法。它是通过对大量数据进行统计，用交互、迭代的方法求出全局最优解。笔者用西部地区的３ 个典型例子说明该静校正方法对于处理地表复杂地区的静校正问题是行之有效的。Static correction is a key basic process in areas with complex surface conditions. This paper presents a static correction method by using the first arrival times in raw seismic data. The global optimized static correction values are estimated on the basis of statistics of large quantities of data by making interactive iteration. The paper also gives three typical examples of western areas to show the effectiveness of this technique in solving the static problems complex areas.
