In the first step,through using the formula of the conformal transformation,a continuous medium with regulation boundary in original area could be transformed to a homogeneous medium with anomalous boundary in complex area,so the new constant velocity field could be more adapt to the current Stolt migration's conditions.
首先,利用保角变换法可将不规则边界的单连通区域转变成规则边界的原理,将规则边界的连续介质场转变成不规则边界的均匀介质场,使该均匀介质场更适应现有Stolt等偏移方法对速度场的要求;其次,对改变了区域的模型地震记录进行常规的偏移成像处理;再利用推导出的反变换公式对成像结果进行反变换,得出模型的真实偏移成像结果。
