| 摘 要： | 叠前深度偏移技术的推广应用一直由于叠前数据量巨大和计算量异常密集而受到限制。为突破这一制约, 对基于频率波数域的快速叠前深度偏移方法进行了算法优化, 在微机上完成了原来只有在大型计算机上才能实现的工作, 并分别对复杂地质模型和实际二维地震数据成功实现了叠前深度偏移, 取得满意的结果。

| Abstract: | A popularization and use of the prestack depth migration has been restricted by enormous data stream and extremely conglomerate amount of calcuation. To break the restriction, the authors optimige the arithmetic technique of the prestack depth migration. Such work which was orignally done on mainframe computers can be realized by PC alone, the authors have achieved the prestack depth migrations of complicated geological model and two dimensional seismic data, and obtained satisfactory results. |
