摘要 近年来发展起来的微分解型叠前深度偏移成像技术 ,在复杂油气勘探的实践中不断完善 ,已经成为复杂地质目标偏移成像必不可缺的工具 .同时 ,随着计算机技术的飞速发展 ,使得并行算法能够极大地提高数值计算的效率 .本文以南黄海地区为例 ,描述了运用二维波动方程叠前深度偏移辛几何算法及并行运算的过程并给出结果 . The technology of pre-stack depth migration developed in these years, become more and more robust in the exploration of oil and gas. It is a powerful and essential tool of imaging. With the progressing of computer, the parallel arithmetic can greatly improve the speed of computing. In this article, I describe the application using symplectic method in Nanhuanghai area.
