| 摘 要： | 时深转换是将地震资料解释成果转化为地质成果的一个重要环节,以油田勘探实际资料为例针对几种不同的时深转换方法进行深入讨论.对于常速成图分区分深度进行幂函数拟合是最理想的办法,对于变速成图在实际应用中需根据不同的资料特征和实际情况选用不同的变速成图方法.通过变速成图计算误差的对比阐述各种方法的优缺点和适用范围,进而根据不同的地质及地震反射条件,选择合适的时深转换方法,以达到最佳的地质成果.

| Abstract: | Time-depth conversion is an important part of converting seismic data interpretation results into the geological results. In this paper, on the basis of the actual data of the oilfield exploration, several different time-depth conversion methods have been discussed. For the constant velocity mapping, the best practice is to proceed power function fitting by dividing the region and the depth. For the variable velocity mapping, we can choose different methods according to different data characteristics and the actual situation. In actual applications, in order to achieve the best geological results, we can select the appropriate time-depth conversion method depending on the geological and seismic reflection conditions. |
