目前,我们在地震资料整理过程中应用的空间校正方法已有多种,尽管各种方法在应用上有所不同,但这些方法都是在垂直构造走向方向上推导出来的。因此,在应用这些方法时,都必须沿着构造倾向方向进行校正。但是,在成图前的构造倾向是不清楚的,因此,在等t_0图完成后,一般是沿着t_0等值线的垂线进行校正,即把等t_0图的等值线走向同构造的走向一致看待,这样就提出了一个问题,即构造的t_0等时线图同
At present, there are many kinds of spatial correction methods that we apply in the process of seismic data collation. Although the methods are different in application, these methods are derived from the direction of vertical structure. Therefore, when applying these methods, it must be corrected in the direction of tectonic orientation. However, the tectonic tendencies before the mapping are unclear. Therefore, after the t_0 graph is completed, it is generally corrected along the perpendicular of the t_0 contour, that is, the contour of the t_0 graph goes to the same structure To unanimity, this raises the question of constructing the t_0 isochrone map
