time to depth conversion

Obtaining velocity model and labeling horizon and doing time depth conversion by using VSP mean velocity and mean velocity of synthetic seismogram to fit velocity;

3通过VSP平均速度和人工合成地震记录反求平均速度进行速度拟合，得到速度模型，进而作层位标定和时&深转换；

In correlation of P wave with P SV wave data, it also needs to consider the influence of polarity, depth time conversion of drilling data and bandwidth of wavelet etc.

在纵、横波资料对比中，又需要考虑极性、井资料的深时转换、子波带宽等的影响。

The author demonstrated the time depth conversion method in detail by using geometry and gave practical calculation steps, and this fulfilled the conversion from seismic image to geological image.

作者利用几何学进行了其时&深转换的详细论证，并给出了实际的计算步骤，即实现将地震成果转换为地质成果的方法。
