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.
