摘要
波动方程三维叠前深度偏移研究 ,已成为近年国内外众多油气勘探科研单位的研究焦点 ,其关键问题之一是借助于软硬件及其匹配的进步 ,以求解决计算量庞大的障碍。作者在本文中从油田实际出发 ,提出了一套并行波动方程辛几何算法三维叠前深度偏移方法与处理流程 ,运用 32节点集群式并行机 ,完成了XJWZ地区 1 5 0km的二维和WJT地区 1 2 6km2 的三维地震资料波动方程叠前深度偏移处理。其成像的效果 ,在信噪比、分辨率、深层复杂构造成像等方面均获得了显著改善
The Research of 3D Wave equation prestack depth migration has now become the focus of study in many institue in overseas and domestics. One of the most important problem is how to resolve the problem of gaint data processing by improvement of software and hardware joint solutions. To solve this problem in Daqing Oil Field, we present a set of parellel wave equation sympletic prestack depth migration flow and compute method, and process 150km 2D and 126km 2 3D seismic data in SW area with our 32 nodes Linux PC Cluster. We finally get an evidently improvement in processing result in S/N ratio, resolution and deep part of complex structure images.
