利用扩展广义互换折射波静校正方法解决MX地区资料的野外静校正闭合差

塔里木盆地MX地区，地表为沙漠，复杂的近地表条件造成有些早期采集的老测线和新测线之间存在着严重的静校区闭合差。在处理中我们应用扩展广义互换折射波静校正方法，通过对该地区折射初至波、低速层速度等参数的详细分析和合理选择，重新连片计算了基准面静校正量，实际处理后较好地解决了MX地区资料的静校正闭合差问题，取得了很好的效果。

Solving the mis-tie problem in MX area via extended generalized reciprocal method (EGRM) refraction statics

In MX area, Tarim basin,there are serious static mis ties between the seismic data collected in the early period of exploration and that in recent years because of the complex near surface conditions of desert. During data processing, we examined the refracted first break carefully and tried to use the EGRM 2D refraction static to compute the datum static value of shots and receivers. The practical processing results show that the serious mis tie problem has been solved satisfactorily.
