常规时间处理(成像)通常在褶皱和冲断层带等地质条件复杂的地区效果不佳。因为这些地区地震资料质量往往不好,有的甚至很差,假构造和位置不准确的反射都是常见的。尤其是在次冲断层位置,由高速超覆岩层造成的畸变极大地扭曲了时间成像。时间处理不考虑倾斜的上覆岩层中的速度变化问题。另一方面,深度成像依据的不是双曲线方法和其它与时间处 Conventional time processing (imaging) is often ineffective in areas with complex geological conditions such as folds and thrust belts. Because the quality of seismic data in these areas is often poor, some are even poor, false structures and inaccurate reflections are common. Especially at the subduction location, distortion caused by high velocity overburden greatly distorts time imaging. Time processing does not account for the problem of speed changes in sloping overburden. On the other hand, deep imaging is not based on the hyperbolic approach and elsewhere
