由于地震勘探的测线只提供了二维的信息,要了解一定面积内的地下情况需要把各条测线的地震剖面进行对比,找出相关的信息推断测线之间的地下情况,才能形成整体概念,这就可能产生相当大的人为误差。三维地震是在一定的面积上采用地下地震信息的方法,
Because the survey line of seismic exploration only provides two-dimensional information, to understand the underground situation within a certain area, we need to compare the seismic sections of each survey line to find the relevant information to infer the underground situation between the survey lines and to form The whole concept, which may produce considerable human error. 3D seismic is the method of using underground seismic information in a certain area,
