在对地震剖面作出明确规定基础上,通过声波合成地震记录、提取子波、剖面波组分析、反求平均速度、模型实验、VSP等方法确定地震剖面的极性,以便准确标定。

Based on clarification of the definition for seismic section, the polarity of seismic section was determined via acoustic synthetic seismogram, wavelet extraction, section wave group analysis, mean velocity inversion, model experiment, VSP, and etc, to facilitate calibration. This work is important for accurate reservoir description.
