地震剖面极性判别直接关系到地震地质层位标定的准确性，现有的合成地震记录判别地震剖面极性方法存在不确定性。围绕这一问题，利用苏北盆地火成岩分布广泛、反射特征明显的特点，提出了基于地震剖面零相位化处理的极性判别流程，并详细叙述了流程每一步的方法原理。通过在SN地区的实际应用证实该方法是适用于苏北盆地的有效方法。

The accuracy of seismic horizon calibration is directly affected by judgment of seismic cross -section polarity. Existing synthetic seismograms, which were used to judge seismic profile polarity, have some uncertainty. In order to solve the problem,a new polarity judgment program based on the zero - phase processing of seismic data was put forward and intro- duced in detail according to obvious reflection features and extensive distribution of igneous rocks in Subei basin. Real appli- cation results in SN area proved that the method is effective and suitable for the Subei basin.
