三维补偿法是通过对二维叠偏剖面的三维补偿空间校正, 使两条叠偏剖面在交点闭合。本文把该空校方法利用计算机技术使剖面闭合、等T0图二次空校和时深转换一次完成, 得到的深度及构造图, 与钻井深度、三维构造图基本吻合。

Throught the 3-D compensation spatial correction for 2-d migrated stacking section, the 3-D compensation method makes two migrated stacking section closed in the intersection point. In the paper, the spatial correction method is used to simultaneously accomplish the section closure, isotime second-order spatial correction, and time-depth conversion by means of computers. The depth and structural diagram obtained by using the method are coincident on the whole with those obtained by drilling.
