| 摘 要： | 将均方根速度转换为平均速度并空间网格化形成平均速度场,再利用VSP、声波测井等数据对初始速度场进行校正得到高精度的速度场。将解释层位与平均速度场匹配做时深转换达到变速成图。这是一种精度较高、操作性较强并适合于NP凹陷的变速成图方法。

| Abstract: | Transforming root-mean-square velocity into average velocity and then using well time-depth relation calibrated by acoustic logging,VSP data and seismic correlation,a 3D velocity field with high accuracy is built.With the help of average velocity field,variant velocity depth mapping can reach high accuracy.The result of the application about this method is very good, because the precision of velocity and depth mapping has improved. |
