针对该区的特点，在资料处理中建立了全区统一浮动基准面，应用折射静校正方法解决静校正问题。

To cope with these problems, we establish a floating datum in the whole area, and perform static correction with refraction static correction.

本文还给出了根据（静校正的）CMP基准面计算地表圆滑面的方法，统一了深度域中速度谱、时深转换和深度偏移的基准面。

A method for deriving the smoothed ground surface from CMP datum of static correction is given to form a common datum for velocity spectrum, time-depth conversion and depth migration in depth domain.
