二维地震偏移剖面只是沿测线进行了一次二维偏移,在三维空间作图时测线交点无法闭合。我们依据几何地震学的原理,应用计算机技术,实现偏移剖面的闭合,达到三维空间上的归位。

There are mis ties between 2D seismic migration sections in the case of mapping in three dimension because they are migrated in two dimension only once along the seismic line. Base on the principle of geometric seismology and with the help of computer technology. We proposed a solution to the problem of mis tie which can make structural map directly by using migration sections.
