单程波动方程叠前深度偏移并行计算与应用
|
摘要
利用单程波动方程炮道集叠前深度偏移方法,建立了相关叠前深度偏移处理流程;在研究地震资料海量数据管理特点和波场外推算子并行算法的基础上,提出了主从模式动态负载平衡并行算法;研究了大规模地震数据并行计算的断点恢复技术,实现了软件级的断点恢复策略。应用自主研究开发的地震叠前成像软件系统对胜利油田BS6探区160km2的三维实际资料进行的生产性处理取得了较好的效果。
The One-Way Wave Equation Prestack Depth Imagimg operators in the hybrid domain are developed into the software and the processing sequence is built.A dynamic load-balance parallel algorithm with the master-slave mode is put forward based on the PC cluster systems.The restart of calculation after interruption is a tough work for parallel computing.A method for restarting the computation is presented and the quite good results are received.The real seismic data about 160 km2 is processed with the self-developed software system-STseis.The quite good geological results are acquired.
