用广义互换法识别漏检地层的能力取决于最佳 XY值。反过来。为确定最佳XY值需要折射层存在某些横向变化。由于折射层中可能不存在横向变化,故位置和方向不同的横向变化可能使最佳XY值无效。
The ability to identify undetected formations using the generalized interchange method depends on the best XY value. in turn. There are some lateral variations in the refractive layer needed to determine the best XY value. Due to the possible absence of lateral variations in the refractive layer, lateral variations of position and orientation may invalidate the optimal XY values.
