【摘要】 波动方程三维叠前深度偏移是近年应复杂地质构造与地震岩性成像需求而发展的一项关键技术 .此项技术与集群式并行机的结合 ,更是将其价格性能比降低至工业生产规模应用水平 .然而 ,波动方程三维叠前深度偏移的实用化还需要诸如地震资料网格化、并行计算负载平衡等一系列配套技术 .本文针对油田实际资料 ,试验了其应用波动方程三维叠前深度偏移的规则化技术 ,并结合地震炮集数据的特点 ,在自组装的集群式并行机上 ,解决了其节点间的负载平衡问题 .本项工作有助于推近复杂观测系统下的地震数据实现三维波动方程叠前深度偏移 .更多还原

【Abstract】 D wave equation prestack depth migration (3DWEPDM) is one of the advancing techniques under the demands of complex structure and lithology imaging in the last several years. Combining with the PC cluster, the cost of 3DWEPDM has now made itself available to the oil industry. However, a series of technique problems have to be solved before successfully applying the 3DWEPDM to the filed data of complex layouts. In this paper, several regularization methods have been tested and the load balance among the nodes of cluster has been considered as well. This work will help to consider the solving scheme of applying the 3DWEPDM technique to the data of complex layouts.更多还原
